Summary: everything's great about it even the forward and backward buttons are far enough out of the way that I'm not always hitting them like every other mouse size is great only complain is that I was expecting the sides to have a more rubber feel and grip a little better. my third finger slips off sometimes under normal usage. the on board adjustability of the mouse is great, too.
Summary: As far as mice go, currently this is the only one I'd pick. It has a nice feel in the hands, adjustable DPI, a 1000hz driver and does not have angle snapping (this is a good thing). I'd always pick optical over laser. The only thing I don't like is that the mouse wheel's sensor seems to get out of sync with the clicks, so when I'm scrolling the scoll will happen half way between clicks, or between the clicks and then again on the click.
Summary: This mouse is a very good gaming mouse! This is an awesome mouse, perfect size, very comfy to the hand and offers perfect precision in-game. Unfortunately, the mouse has a very thing cable which bugs an awful lot..... I have had this mouse for 3 weeks now and it keeps turning itself off and back on again. From what I have read online, this is very common with all G400's and can be caused even just by the wire hanging loose of an edge.
Summary: For those who don't know lift off distance is the distance the mouse will still track while in the air. This mouse has a rating of about 4 CDs, which is very high (bad). Basically, if you're a gamer who lifts the mouse off the pad at all while moving (most prominent in first person shooters) your cursor will continue to move while in the air, which completely knocks off your aim.
Summary: Good mouse with nice sensitivity one problem which has developed after 6 months of use is that when you use the middle mouse scroll the middle button gets clicked without me actually clicking it so I have to be careful but otherwise it's great.
Summary: Really good mouse for the price. I game from a G500 and although the build quality isn't as good it's still comfortable to use for a long amount of time. Doesn't have weights and the mouse feels quite light which is a change from the G500. I'd recommend this mouse to anyone who's looking for a decent mouse (not just for gaming) which doesn't break the bank.
