"Fantastic media/work mouse. Sub par gaming mouse."4.0 starson by erikcullx
Pros: -Excellent hotkey setup for media and work or school
-Keyboard feels smooth and natural to type on
-The built in keyboard calculator is insanely handy
-Mouse is very ergonomic and the buttons are positioned well
-Charging cradle is very convenient
Cons: -If you are looking for a pure gaming combo I would look elsewhere
-Bought this for casual-medium gaming and was disappointed as the additional mouse buttons aren't picked up in the games I play
-Dual mouse wheels take some getting used to
Summary: If you're like me and do a lot of media tasks, are a student/employed and use the microsoft suite and calculator functions frequently then this is a perfect combo for you! In that sense I would give it 5/5 stars.
If you do all of the above and some casual gaming I would still recommend it and give it my offical 4/5 stars (As this is exactly what I do with the product)
But if you were looking for something to satisfy your gaming needs you should probably look elsewhere. As a gaming combo I would rate it at about 2.5/5
** Browsing over the most recent reviews, I have absolutely zero mouse lag with MY combo and it works perfect with Windows 7 x64.
