Reebok Nano X3: One minute review

The Reebok Nano X3 has garnered a reputation for its performance and style in the CrossFit domain. While it marks the latest in a long line of iterations, the Nano X3 is unique in being Reebok’s most versatile Nano shoe to date, and one of the best gym shoes around.

In the design department, it adopts a minimalist and sleek aesthetic, which is bound to appeal to a wider audience of gym enthusiasts. There’s also a variety of color options on offer, from Future White to Core Black, catering to different tastes.

Performance-wise, these shoes shine in many gym scenarios. The 7mm heel-to-toe drop, though higher than previous iterations, provides exceptional stability, especially during weightlifting sessions. The standout feature is the Lift and Run (L.A.R) Chassis System, a game-changer for agility and support. This upgrade sets it apart from earlier Nano models.

The shoe's breathable FlexWeave upper ensures comfort and ventilation, although it may not match the durability of some competitors, such as the Nike Metcon 8. Another minor downside is occasional slippage of the insoles, particularly in the heel. Tightening the laces or swapping out the insoles might help here, though.

While the Nano X3 shines in most gym settings, it's not the best option for running due to limited cushioning. Its rigidity, which makes it ideal for heavy lifting, also means it might take some time to break in. However, this is a top-performing and versatile gym shoe that will suit the needs of most fitness enthusiasts, especially lovers of CrossFit and HIIT.

Reebok Nano X3: Price and availability

• Around $140 in the US
• Under £110 in the UK
• AU$199 in Australia

The Reebok Nano X3 is available to buy now directly from Reebok, as well as most big online fitness retailers. They have an RRP of £110 in the UK, $140 in the US and AU$199 in Australia. 

However, these prices are largely dependent on the colorway. For example, some variations in the UK, such as the Cloud White model, are currently on sale and available from as little as £72, offering excellent value for money for a gym shoe of this caliber.

Reebok Nano X3: Design

• Stylish and minimal 
• Revamped FlexWeave upper
• Available in various colorways

Dubbed "the official shoe of fitness" by its creators, the Nano lineup has seriously shaken things up in the fitness world since its first release way back in 2011. 

Multiple iterations later, the 2023 edition of the series comes with a revamped FlexWeave upper that promises to be more breathable, a fresh tread pattern, and a whole new chassis system that helps the shoe perform well across different workout types.

What stands out about the latest Nano, however, is its pared-back design. Reebok has gone for a very minimal aesthetic this time round, which will likely appeal to a wide remit of gym goers. The only thing no longer minimal about it is the lift: the 7mm heel-to-toe drop may be a little high for some. Those who are used to older versions of the Nano, which featured a 4mm drop, might need some time to get used to it. I found that the higher drop still offers great stability - especially for lifting heavy weights.  

The Nano X3 shoes are available in a host of colors, including Future White, Core Black, Hunter Green, Cold Grey, and many more.

• Design score: 5/5

Reebok Nano X3: Performance

• 7mm heel works well for heavy lifting 
• L.A.R Chassis System offers support for high-impact activities
• Insoles can feel a little slippy
• Breathable FlexWeave upper helps keep you cool

While looks are important, what really matters when it comes to buying a gym shoe is performance. So how do these training shoes fair when push comes to shove?

They actually perform brilliantly in most gym scenarios thanks to their versatile design, breathable upper and solid base. With the higher drop, I could still plant my heels solidly on the ground and power through. It gave me a grounded feeling without squishing me into foam like some other high-drop training shoes might do.

The biggest upgrade in the Nano X3, however, is the all-new Lift and Run (L.A.R) Chassis System. This midsole tech allows the heel to change its rigidity depending on your activity. While it might sound like nothing but marketing guff, you’ll come to realize - after using the shoe a few times - that this component really does help up the ante when it comes to performance. Whether pushing through a heavy lifting session or taking part in an agility-focused workout that requires sprints and jumps, you can really feel the chassis system doing its job and giving you that push you need - especially compared to previous Nano models that lack this feature. 

During sweaty, high-intensity workouts, the Nano X3 keeps things cool with its breathable knit upper made from Reebok's trusty FlexWeave material – a familiar sight from the previous Nano versions. This ensures your feet get the air they need and allows for some flexibility. It’s not quite as durable as you might find in some of the Nano’s rival shoes, such as the Nike Metcon 8, for example, however, the toe box has been reinforced to reduce the risk of puncturing the shoe's upper. So, while you might not get tank-like durability, you're definitely getting a more forgiving forefoot and midfoot.

Negatives? Well, I did find the insoles a little slippy here and there, especially in the heel when I needed to push myself off a surface at speed. This required me to tighten the laces a little more than I would usually, which did solve the problem somewhat. But you might need to swap out the insoles altogether if you find the slippiness a persistent problem.

You should also note that the shoes’ rigidity in the heel and midsole means they’re not well suited for long-distance running.

PocketBook InkPad Color 2: one-minute review

It’s fair to say that color ereaders still have a way to go before they become mainstream, but one company looking to make sure we get there is PocketBook. The European brand’s InkPad Color 2 ereader takes what worked on the original model, improves upon it slightly, encases it in a sleek, new design and throws in waterproofing to make sure you can take it on your next poolside holiday. 

If you primarily read comics and graphic novels, then the InkPad Color 2 isn’t a bad option and I enjoyed using it more than its predecessor. Firstly, I found it faster and more responsive than the original – read my PocketBook InkPad Color review to find out more – thanks to a new quad-core processor. I also like the fact that it’s got IPX8 waterproofing (the previous model had none) and adjustable light temperature which strains the eyes less when you’re reading in the evening or at night.

I also found that some colors look marginally better on the screen – that’s thanks to a new filter. But it retains the older-generation E Ink Kaleido Plus display found on the older model when the latest color screen to be had is the Kaleido 3. While the colors are still not as saturated as I would have liked, some hues do look richer and they get better as you increase brightness. Other colors, however, still look quite washed-out (muted) and I’d probably hold out for a color ereader till someone decides to use E Ink’s Gallery 3 screen technology that promises saturation similar to what we’re used to seeing on our phones. Sadly the screen also lacks in contrast when compared to other similar models.

The InkPad Color 2 features a small speaker (you can see the grille on one edge of the device), but I think it’s unnecessary – the sound is decent, but it doesn't get very loud and, with Bluetooth 5.0 support, you’re better off pairing with a set of headphones to enjoy audiobooks.

While the improvements look good on paper, the user interface is still not as streamlined as we’ve seen on other ereaders and you can’t purchase content directly from the device’s book store if you live outside of the European Union. 

Still, it’s good to know that you get these improvements – as incremental as they may be – for the same launch price as the older InkPad Color ereader.

PocketBook InkPad Color 2 review: price and availability

• Announced April 2023
• Available to buy now for $329 in the US
• Available in UK and Australia as international imports via Amazon

Two years after PocketBook announced the original InkPad Color ereader, it released the second-generation model… and for the same price too! Which is good news as there’s more bang for your buck here than before.

Available to buy directly from PocketBook or from some third-party retailers, the InkPad Color 2 will set you back $329 in the US. If you happen to be in the UK or Australia, your best source of picking up the InkPad Color 2 would be Amazon UK and Amazon AU respectively, where you can get the German import for about £345 and AU$595 respectively.

That’s not a bad price for a 7.8-inch color ereader, although for a little extra money ($399 in the US), you can get the older Onyx Boox Nova 3 Color that also has writing capabilities. 

A more up-to-date color ereader would be the Onyx Boox Tab Mini C, with a 7.8-inch E Ink Kaleido 3 screen, an octa-core processor and running Android 11 for a slightly smoother user interface and full-featured writing capabilities, costing $450 / £450 / AU$765.

While still not cheap, the InkPad Color 2 could well be worth your while if you really want a color-screen ereader and don’t need to take notes on it.

PocketBook InkPad Color 2 review: Design and display

• Refreshed design reminiscent of PocketBook Era
• Good-sized screen
• Older-generation display technology with new color filter

All PocketBook ereaders have a signature design – either rounded or cut-off corners. The latter came with the PocketBook Era and the InkPad Color 2 inherits a similar, more modern look compared to the rounded corners of the older model. I’m a real fan of this design aesthetic – it’s refreshing and the InkPad Color 2 looks even better thanks to the metallic silver (what PocketBook calls Moon Silver) trim around the side of the chassis.

That’s not the only design aspect the InkPad Color 2 inherits from its Era cousin – the PocketBook branding is now on the lower left corner of the tablet compared to being in the center (as in the older InkPad Color) and matches the color of the silver trim.

The front bezels and the rear panel is black plastic that is a magnet for oily fingerprints, and given the rear is textured, not that easy to wipe off either. 

Barely visible on the edge of the lower bezel are four control buttons. These are marked but, again, quite faintly. I’m not a fan of their placement – they’re so close to the edge that I find it easier to tap on the screen to turn pages. I had the same issue with the PocketBook Era too where the buttons aren’t quite where my thumb sits on the side of the device. While I didn’t quite enjoy the buttons on the older InkPad Color either, at least they were higher up on the bezel so my thumb could rest on the two middle ones. 

I still stand by my statement that the buttons on both models of the InkPad Color should be slightly raised or textured differently as they’re hard to find by feel alone and it becomes difficult to put the device to sleep if you’re reading in the dark (which I often do).

Where the older color ereader had a separate power button on the bottom edge, the button on the right corner of the lower bezel doubles up as the sleep and power buttons. You need to go into the device’s settings pane to set that up though. I customized mine to work as a sleep button with a single press and a double to power down. The left corner button gets you to the home screen (and can be customized for another function), while the middle two are the page-turn buttons.

The lower edge now just houses the USB-C port for charging and file transfer, beside which is a tiny indicator light that glows when you press a button, when the screen refreshes or while charging. The right edge has two tiny slits which is the speaker grille.

All in all, it’s a clean, minimalistic look that is now waterproof. An IPX8 rating means the InkPad Color 2 can survive in 2 meters of water for up to 60 minutes.

As before, the main selling point here is the color screen. For me, 7.8 inches is a good size – decent amount of screen real estate so you don’t have to constantly keep turning pages and, thus, eating into the battery life, and it’s still portable. That said, this screen doesn’t always display full pages of a graphic novel – depending on how the file has been set up.

What I’m not quite a fan of is the fact that a 2023 ereader model is using an older-generation screen technology. PocketBook has stuck with the E Ink Kaleido Plus screen it used in its original color ereader, but has tried to improve on it by using a new color filter. This filter, PocketBook says, adds more saturation to the colors displayed compared to the older model. While that’s ever so slightly true for some hues, the overall results are quite mixed. For example, there are some blues that look a lot richer compared to what I saw on the InkPad Color, but some reds and browns still look washed out.

The screen retains a 300ppi resolution for grayscale reading (black and white only) and has just 100ppi resolution when viewing in color. The latter is quite low, considering you can get ereaders with 150ppi color resolution. This may not mean a lot to you if you’ve never used a color ereader before, but I found a significant difference when comparing the InkPad Color 2 side by side with the newer Kaleido 3 display on the Onyx Boox Tab Mini C (see the Performance section for details).

What the InkPad Color 2 does better than its predecessor is offer adjustable light temperature. To be able to change the frontlight hue to warmer tones in the evening or night reduces eye strain and can help maintain your sleep pattern. One thing to note, however, is that if you are reading in color, warmer light will affect the colors slightly. 

The InkPad Color 2 gets what PocketBooks calls its SmartLight functionality – when selected, the device will automatically adjust the frontlight temperature to suit the time of day. While that’s nice to have, I found that the auto-selection of the warm tones are just too warm and the display is just too… jaundiced for my liking.

PocketBook InkPad Color 2 review: Software and user interface

• 1GB RAM and 32GB GB internal storage
• Arguably the best file format support of any ereader brand
• User interface could do with some improvements

As I’ve mentioned before, the InkPad Color 2 gets a new processor – while no specifics have been revealed of which precise chip it is, it’s now a 1.8GHz engine compared to 1GHz in the older model. This is paired with 1GB of system memory (or RAM), which might not sound like much but is more than enough for a low-power device like an ereader.

Where the previous model had 16GB of internal storage alongside a microSD slot that can support an additional 32GB, the second-generation color ereader gets non-expandable 32GB of storage. This is usually a lot if you’re mostly storing a library of ebooks, but if most of them are comic file formats – they are typically larger than your average ebook – and audiobooks – which can be larger still – you could eat through that storage space. Even then, it’s a lot!

As with any PocketBook ereader, the operating system is Linux based and I’m still not quite a fan of the user interface. It’s not too bad, really, but it’s not as smooth and streamlined as other ereader setups from the more popular brands. Even Onyx’s Android-based interface is a bit smoother, but the staggering number of customizations available there can be a little mind-boggling. 

That said, I like the fact that audiobooks are stored separately from ebooks on the PocketBook, making them easier to find when you want to listen rather than read. Another thing I like about the audiobooks on the InkPad Color 2 is that it continues playing if you go back to the home screen or jump into your library to decide what you’d like to read next. In fact, it will continue playing even if you open an ebook and start reading… handy if you can multitask like that.

Updates to the user interface since I tested the PocketBook Color have helped make the UX a little better, but I still find it lacking. While the general layout of the home screen is good, I would like to be able to sort my library out as I see fit. On PocketBook ereaders (all of them), your library gets sorted alphabetically by title, but you can filter by author name.

Another thing to commend PocketBook on is the staggering number of file formats its ereaders can support. The InkPad Color 2 can handle a staggering 36 file types, which includes document, images and sound. That’s very impressive indeed. You may not even have some of these file formats, but it’s good to know that the support is there.

The onboard book store, while accessible in any region, will display prices in Euro. You can set up an account if you live outside of Europe and don’t mind purchasing in a different currency. That said, the store doesn’t have a lot of titles you’ll see from the top publishing companies, so your choices will be quite limited.

PocketBook InkPad Color 2 review: Performance

• Improved performance over InkPad Color and Era models
• Speaker sound is good
• Screen color resolution is disappointing

Giving the InkPad Color 2 an updated processor was a good call. Issues I noticed in the PocketBook Era – sluggish refreshes, slow loading of page numbers – are no longer a problem. However, I am a little disappointed with the screen. 

Despite the 300ppi in grayscale, the screen lacks contrast. A side by side comparison with other monochrome ereaders shows a distinct lack of sharpness to the text displayed on the screen. This makes the InkPad Color 2 comparatively harder to read indoors unless you raise the brightness up. During my testing, I found that the screen looked best at 90% brightness even when using it in a well-lit room. That, however, becomes an issue if you’re reading at night with your room lights off as it can strain the eyes (even if you change the light temperature to warmer hues).

The lower color resolution is also an issue – which is evident when comparing alongside the Onyx Boox Tab Mini C, a 7.8-inch color ereader sporting a Kaleido 3 screen. While some colors look better on the InkPad Color 2 compared to its predecessor, I could see lines and textures that kept distracting me while I was reading a volume of The Sandman graphic novel. Other colors look a lot better on the Onyx ereader, with no texturing evident at all and I think I would pay extra to have a better screen experience.

Aside from the disappointing screen, the new processor has made page turns faster, which was a complaint I had with the InkPad Color 2’s predecessor. The screen is also more responsive than before. However, the refresh rate isn’t as good as what I’ve seen on other ereaders and ghosting can be a problem till a page refreshes. For example, if you’ve selected some text to highlight, you will see light ghosting within the highlighter’s circular color choices. At other times, the cover page takes a second or two to refresh to look its best in color.

If you’re a fan of audiobooks, the built-in speaker is pretty good, but I still think it’s unnecessary. The sound doesn’t get as loud as I’ve experienced with some Onyx Boox models, and I found using Bluetooth headphones an easier experience as it gave me the freedom to move around without the sound getting too faint. Where the sound quality from some Onyx Boox speakers was tinny, the InkPad Color 2 in fact has better sound despite its mono speaker. Not bad, PocketBook!

Battery life is also quite good. The 2,900mAh pack inside will get you about 4 weeks between charges, but that will depend on how you use the ereader. Just reading about 30 minutes a day can get you up to 5 weeks between charges, for example. However, if you read longer or listen to audiobooks more often, you could get less than 4 weeks. The screen brightness setting can also affect the battery life.

Topping up that battery can be a little over an hour from 30% to full, depending on the kind of USB-C cable you use. The one packaged with the ereader itself is quite slow and took me 2 hours and 23 minutes to go from 34% to full. I used an USB-C Type 3 cable plugged into a 65W GaN wall plug and that took1 hour and 17 minutes to go from 30% to 99%.

• Performance score: 3.5 / 5

If you think the PocketBook InkPad Color 2 isn't for you, take a look at a few other alternatives below, with a full specs comparison to help you choose.

How I tested the PocketBook InkPad Color 2

• Used it to read for about 7 weeks, in both color and B&W
• Used it to listen to audiobooks
• Compared it directly to other 7-inch and 7.8-inch ereaders, both color and grayscale

I’ve used the PocketBook InkPad Color 2 as my main ereader for just under two months now. While it came preloaded with a lot of titles already, several were in European languages (German, Polish, etc), so I sideloaded a bunch of my favourite DRM-free titles that I own. 

As a voracious reader, I used the InkPad Color 2 to read a minimum of 2 hours a day, sometimes more. I did browse the onboard store out of curiosity to see what was on offer, but refrained from purchasing anything.

While most of my reading was word-heavy – so ebooks in grayscale – I read a couple of graphic novels on it to test its color rendering and resolution. I compared how these same titles were rendered on the Onyx Boox Tab Mini C to come to my final score of the InkPad Color 2.
