Heading on to the performance tests of the extended Level 20 RGB pad, buyers don't have to worry about anything. The pad is flawless in terms of tracking, which I tested with three mice. A Tt eSPORTS Iris Optical—it uses a rather cheap mid-tier PMW3325 sensor—and two high-end tracking units, a PMW3360 and HERO inside a Cooler Master MM530 and Logitech G PRO Wireless respectively. As expected, I ran across no issues.

These graphs show fifteen horizontal swipes with each mouse. If anything strange should happen with the sensor, this test (and others that aren't as impressive visually) will show it. I also did some in-game testing in CS:GO and Overwatch.
Lighting
RGB lighting is basically the main selling point of this and most other Level 20 Thermaltake products. Its light show is great and surprisingly bright. I have reviewed a few other soft mats with RGB lighting in their edge stitching, but this one is by far the best-looking. Transitions are pretty smooth and colors vivid. Not only the edges, but also the TT logo on the plastic panel lights up as specified by your settings.
The Software driver is TT iTAKE, which is the AIO software for most new Thermaltake devices, including their cases. It's not the most lightweight, and the design leaves something to be desired, but overall, it's usable. With TT RGB Plus, you have the option to synchronize your other (mostly newer) RGB-capable Thermaltake devices, as well as Razer Chroma-enabled products.
You can also control the settings with Amazon Alexa, making this (and the Level 20 hard pad) the first smart mouse pad that I'm aware of with that capability. Is it a necessity? Absolutely not. Is it cool? Yes, absolutely.
