Pros: Small. Kinda cheap. Works ok as long as the receiver is not getting interference.
Cons: Range is limited, even thought the USB dongle is HUGE! It picks up interference from all kinds of things. Sometimes the mouse will move just fine, making you think it is connected well, but then you 'click' and nothing, so you move the mouse and it moves, then you 'click' again and still nothing....
Cons: Left click too stiff... I do lots of detail clicking/double-clicking and found my wrist was getting sore from trying too hard to double click. The stock "wired" mouse that came with my Sony system has much better click action.
Summary: its a decent mouse, but beware that there will be no fast scrolling with it. so overall, i would not recommend this mouse to anyone, its just a hassel.
Pros: um....i guess its an alright mouse, cept for the middle wheel.
Cons: the middle scroll wheel is extremely inconvenient, it is very hard to scroll, making it quite difficult to quickly search through just about any document, large or small it just feels really..."jelly like".... and has a lot of resistance
