This si my main for two months now and is one of the best mice from the Chinese market that I have tried so far (besides empirical mesaurments of course). Main buttons are near perfect (rattle what?, no pre travel, little post travel on the right, no post on the left, no side movement, no bottoming, tight as hell), center switch click is moderate, side buttons are mid (almost no pre trvl, ~1mm post trvl). And there is a very grippy coating which is unusual in sub 50 price range. Mouse creeked once when I tried it for the first time and now it's gone. Stock skates = garbage. Maybe another brand with QC variety, or yours was slammed during shipping. I'll wait for the click latency test from other reviewers.
