I'm posting this here because some of you may or may not be interested in this mouse and I don't want OCN users to see this review on youtube and be fooled by a completely incompetent mouse reviewer. This reviewer claims that the Abyssus has positive acceleration and is able to hit negative acceleration.... BUT:
THE ABYSSUS DOESN'T HAVE POSITIVE OR NEGATIVE ACCELERATION!
I have personally used two different abyssus on a total of four different cloth mouse pads, three hard pads and a piece of friggin cardboard from a cereal box and I NEVER experienced positive or negative acceleration. And I specifically tested for these because I'm very sensitive to either of them. The only legit flaw which forced me to return them was that they jittered on my cloth pads which this reviewer didn't even touch on......
