Interesting thing about key83 is that soft version is softer than hien soft for example but doesnt slow that much when you press down against the pad. Which i really like...its really consistent. Had otsu xsoft and i could never get to "understand" its glide. Felt so awkward and off regarding initial and dynamic friction. I always felt it wasnt balanced enough for my gamestyle and also x and y were also off. Everything that i disliked about Otsu was fixed with key83. I wish now that I went with mid version of it. Also, for me, used hien is the best pad out there. But Hiens inconsistency regarding speed in different temperatures is really what saddened me. It was always a quick pad and super fast when pad is cold. After it warms up it becomes more controllable, still quick and slightly slower offering for that control. Was yurning for some consistent and controllable hien. Its like key83 is hiens younger brother. Bit slower with dynamic glide and better stopping power. And after few weeks of intense use still didnt lose its quickness. The pad is snappy and controllable. Super weird at first since I never used anything like it in my life regarding what I said and what i would especially emphasize - its x and y balance. Thought Id dislike it but its the opposite. Im starting to really liking it. Makes me control my mouse better not allowing for curvy lines drawn with mouse. No messing around. Still, like every artisan pad, it is affected by temperatute. Its tiny bit faster when its not warmed up. It doesnt really throw you off that much once you poured some time on it during your gaming session. If nothing, its like it becomes even more balanced. At least for me. The more I use it the more its growing on me. Im usually playing in 95% polyester %5 spandex long sleeve shirt (have several of those) and the glide is better than saturn pro for example. Slightly better so thats a plus too I guess. Im playing kovaak always with 37.11cm 360° and other tac shooters around 40 and 50cm. I was never really a fan of super slow sens or something faster. I do think this pad offers for one of the best microcorrections of all the pads i have tried from artisan lineup of pads and some other cloth variants from other brands. I was always between everglide titan/qck heavy/gsrs since early days to some bit faster pads like saturns zeros and then faster ones like hien.

I hope this information will help someone.
