The SteelSeries QcK Limited is an exceptional mouse pad; if you are looking for one with an extremely smooth, very densely woven surface that provides a smooth yet controllable glide, then the Limited might be one of your top choices. Even though it comes rolled up, it lays out flat within a few minutes (you can help it do so by carefully, but not too tightly rolling it up in the opposite direction), and in a few hours, it gets even better, so you won't have to wait days to utilize this mouse pad to its fullest.
As for the build quality, it is almost perfect; the only thing I can nitpick on is that the stitching along its edge has some parts that stick out. Otherwise, it is perfect; both the surface and underside are completely even. Thankfully, there is no raised logo on top of the surface, so the mouse can glide around the whole pad freely.
Objectively, this mouse pad is among the best ones currently available. If you like the surface, it can easily be your faithful companion for long hours of gaming, working, or just casual browsing. I would gladly recommend it to anyone looking for a mouse pad in the two available sizes.
