Sales rep...? xD
Nah but really, it's a nice pad if you're into the kind of glide that frosted glass provides, or prefer very low static friction. I have one. ;3 I found out myself that the Frostpad in particular feels pretty much like a chalkboard.
For me, though, that's kinda where the luxury ends. I use it casually because I like the glide and the feel of it, and it looks nice. I wouldn't use it competitively, though. I can't speak for certain about any other optical sensors, but all of my 3366 mice had tracking issues on black pad (the most compatible color). No skipping or spinouts or anything of the sort, but just less responsive tracking. It felt like "artificial input lag" if that makes any sense. I keep my actual system/game latency very low, and I was definitely able to notice the difference between my Frostpad and my other surfaces, which tracked flawlessly.
Edit: Apparently nobody else has experienced this, though. I suppose it might just be that I'm not used to it. Can't imagine why any other sensor would perform worse than the 3366 does on this pad, so you'll probably be fine with yours.Edited by Avalar - 6/20/17 at 10:27pm
