Summary: After using this for some time, I have come to the conclusion it isn't a great mouse ! Awkward to use, doesn't sit in the hand nice, caused no end of wrist pain, charging cables broke and stopped working, got a replacement from Microsoft , same thing happened again! Silly desktop charger cable thingy? What were they thinking. stopped using it and got myself a wired Roccat XtD mouse, which is in a different league ! Save your money !
Summary: The best mouse I could find, just loved it. Right size. Actually bought two. But the same problem with both. The battery recharge stopped working and the cost too high to have silly faults like that.
Summary: well I have had this mouse for over a year now and it was by far the worst mouse I have used to date. As a pc gamer I expect more from Microsoft. So here are the problems. After about a week the wheel stoped clicking so it was a smooth and hard to select stuff in game (gamers will know what i mean). After about 2 weeks the rechargeable battery was only lasting a couple of hours a replacement aint that cheap!
Summary: I bought this as my first gaming mouse, primarily because Amazon were offering it at £40 (RRP was about £80 at the time) and as such, it seemed to represent good value. 18 months on, I'd have to concur that it is pretty solid performer overall, though I do have an issue with the scroll wheel - something appears to have worn away inside, hence the three star review: For a premium item with a premium price tag to match, I'd have thought it would be reasonable to expect...
Summary: Purchased as a replacement for a Logitech Performance MX, that had terrible battery life. Although not as nice to hold as the Performance MX the battery life is excellent and the charging cable is much less intrusive. Quite a large mouse so be careful if you have small hands.
