KUU LeBook 12.6 2-in-1 convertible review: A cheaper Microsoft Surface Pro alternative

Is the KUU cool? There are a lot of Windows 10 tablets to choose from beyond the Microsoft ones. The KUU LeBook is perhaps the closest in terms of visual design and performance while costing potentially hundreds of dollars less, but it misses the mark in a few areas.

The KUU LeBook 12.6 is a Windows 10 detachable in the same vein as the Surface Pro series. Its design and features are clearly inspired by the successful Microsoft tablets with certain changes and cut corners in order to keep prices significantly lower. One of these changes is the use of an older Intel 8th gen Core U-series CPU instead of the latest 11th gen versions currently found on most PCs in the market today. This review will explore all the other differences users can expect if purchasing the cheaper LeBook instead of a more traditional Surface Pro.

Competitors to the LeBook include other Windows 10 tablets or detachables like the Microsoft Surface, Lenovo ThinkPad X12, or Dell Latitude 12 7210 2-in-1 all of which retail for higher prices. However, the LeBook is unique with its slightly larger 3:2 12.6-inch display instead of the usual 12.3-inch or 12.5-inch screens. The manufacturer has yet to finalize the price of the LeBook as it is not yet widely available at the time of publishing.

Case

The metal chassis is a highlight of the LeBook as it feels close to the quality of a pricier Surface Pro. The metal stand on the back could have been more rigid or thicker, however, as it warps somewhat easily.

The base consists of Alcantara and a faux leather bottom texture. Though it looks good with a high quality feel, It's too flexible and susceptible to twisting which negatively impacts the typing experience. A firmer and more solid keyboard deck would have been better.

Size and weight are ever-so-slightly larger and heavier than the Surface Pro 7 which correlates with the slightly larger 12.6-inch display. The screen-to-body ratio is higher on the KUU regardless. Using the keyboard base adds about 308 g to the weight of the tablet.

Communication

There is no Wi-Fi 6 support likely to save on costs. The integrated 1x1 Intel 3168 offers real-world transfer rates of only around 350 Mbps to be over 4x slower than pricier laptops with the Intel AX200 or AX201.

Accessories and Warranty

The retail box includes the AC adapter, detachable keyboard dock, and an active pen stylus. The standard one-year limited manufacturer warranty applies.

Input Devices

Keyboard

The typing experience is worse than on the Surface Pro series mostly because of one drawback: the base doesn't sit completely flat on the table. As a result, the back of the keyboard base will always bounce up and down when typing which impacts the feedback of the keyboard keys. Typing feels spongy since you're pushing down on the whole base with each key press.

There are two LED indicators on the left palm rest of the keyboard base. These lights are relatively bright and we wish they could have been a bit smaller to be less visually obtrusive.

Touchpad

The clickpad is larger than the clickpad on the Surface Pro 7 (10.8 x 6.4 cm vs. 10.2 x 5.3 cm). Its advantages end there, however, as almost everything else about the LeBook clickpad is worse. Its surface is sticky when gliding at slower speeds which leads to a jumpy cursor. Multi-touch inputs are also finicky, unresponsive, and oftentimes inaccurate. When trying to drag and drop, for example, the system would frequently register our actions as zooming in or out instead. The integrated clickpad buttons, while loud and clicky, take a lot of force to actually press. And finally, the clickpad is not Precision-enabled meaning any Microsoft Precision features are out of the question.

Display

The 12.6-inch BOE TV126WTM-NU0 IPS panel is the first to appear on our database. Certain attributes like response times and color coverage are slightly worse than on the Surface Pro which thankfully won't matter very much when web browsing. Other attributes like contrast ratio and maximum brightness are meager and representative of a budget panel.

The display is decently calibrated out of the box despite the cheap starting price. Color temperature is slightly too cool, but a calibration addresses this without any issues. The final average grayscale and ColorChecker deltaE values of just 1.5 and 1.27, respectively, are better than we had initially expected. Shades of magenta may be more inaccurate than other colors, however.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
33.2 ms ... rise ↗ and fall ↘ combined↗ 19.2 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 86 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (23.9 ms).
       Response Time 50% Grey to 80% Grey
42 ms ... rise ↗ and fall ↘ combined↗ 22.4 ms rise
↘ 19.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 56 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (37.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 15366 (minimum: 5 - maximum: 2500000) Hz was measured.

Outdoor visibility is poorer than on most other tablets since the display is dimmer. Expect a lot of unavoidable glare when under most outdoor conditions.

Performance

Processor

CPU performance is roughly 30 percent and 45 percent slower than the latest Core i7-1165G7 in single-threaded and multi-threaded workloads, respectively. Though significant, the difference is not very noticeable for simpler tasks like web browsing or word processing.

Storage Devices

Internal storage is spacious at 512 GB with transfer rates similar to most SATA III SSDs. The lack of an SD card reader means is less of an issue when the internal drive is as large as most laptop drives.

GPU Performance

The UHD Graphics 620 is poor by today's standards where Radeon RX Vega and Iris Xe models reign supreme. This won't be an issue for 4K streaming or non-gamers, but even the slightest bit of editing or gaming will benefit significantly from upgrading to the Surface tablet or any other device with AMD Zen or 11th Intel Tiger Lake CPUs.

System Noise

The internal fan is noisy and it pulsates frequently. Even simple actions like web browsing will initiate the fan whereas it would remain silent on most other tablets and ULV laptops. Expect the fan to pulse in the 36 to 41 dB(A) range under most conditions or up to 45 dB(A) when running higher loads like games.

Temperature

Surface temperatures when idling on desktop are warmer than expected at up to 41 C and 36 C on the front and back hot spots, respectively. Running higher loads will kickstart the internal fan leading to a slightly cooler hot spot of 37 C on the front while the back will be slightly warmer at 40 C. The warmth is noticeable when handling the tablet, but it's thankfully cooler around the edges and corners to not be distracting.

When running Prime95, the CPU would boost to 2.4 GHz for about 30 seconds until hitting a core temperature of 77 C. Thereafter, clock rates would fall and cycle between 1 GHz and 1.7 GHz in order to maintain a cooler temperature in the 60 C to 65 C range. Turbo Boost sustainability is therefore limited on the LeBook since it is a tablet, after all.

Running on battery power will not limit performance. A 3DMark 11 run on batteries would return Physics and Graphics scores of 6186 and 1689 points, respectively, compared to 5384 and 1743 points when on mains.

Power Consumption

The system consumes slightly less power than on the Surface Pro 7 Plus when running comparable applications. However, the savings of just a few watts pale in comparison to the tremendous gains in performance that the Microsoft tablet is able to offer over the LeBook.

We're able to measure a temporary maximum draw of 38.9 W from the small (~6.3 x 6.3 x 3 cm) 45 W AC adapter when running Prime95 and FurMark simultaneously before thermal limitations kick in. The aforementioned Surface Pro 7 Plus can draw significantly more at up to 62.5 W due to the higher Turbo Boost potential of its newer processor.
