Right.
Ive tested it fully. And here are my findings.
I dont get any of the problems that people claim to have, like the slow startup if its been to "sleep", or the rocking due to unlevel pads. I have only had one problem thus far, and that is that after a restart, about 20mins ago, the mouse didnt work at all, despite being connected up properly. But a restart fixed that. Its only happened once since i got it, so i cant comment on if its a isolated incident or not.
Its general feel is great, but my one major gripe, is that the middle click (on the wheel), is hard to do without hitting the side scroll clicks as well, and it sounds a little clunky when it does click in the middle. No biggy though, it could just be the way im using the mouse.
I dont like it that the software doesnt support sidescrolling yet. A bit of a pointless feature if i cant use them, or at least program them to something else. It`d be nice to be able to program scroll left/right to keyboard keys, so then in game i can have them set to lean or summit, until games fully support side scroll buttons. Another problem i have with the software is that it doesnt install proper drivers. The Logitech suite has to be running in the background to have the mouse`s extra buttons working.
Overall, im impressed. And the minor niggles i have are probably because i got used to my MX700, which if i remember correctly, i also had gripes with till after about a week of usage.
As for the problem i had. Ive only experianced it once, and it may be an isolated incident, but i`ll post back if it happens again.
Well worth a buy though imo.
