Pros Works on nearly all surfaces (just not glass from my experiences). The button on the side is surprisingly useful. The grippy sides make it easy to use.
Cons The battery life isn't great, though I don't think it's a huge deal. The scroll thing is a bit smooth though you get used to it after a while.
Pros Works on just about all the surfaces I used it on.
Cons LIfe of the nano receiver doesn't seem to be very long.
Summary The first MS4000 mouse I bought I had for 2 days before having to take it back to replace it. I have now had the second one for almost 4 months and it is now dead with the same usb device error as other people have commented on at numerous sites. The nano receiver in my opinion needs to be built better than it is. If it weren't for this it would be a great mouse. I guess I will just go back to my 3yr old Logitech wireless mouse until it dies.
Pros Easy to set up.
Cons First one worked about three weeks and then when switch activated blue light would just flicker on and then go off. Replacement (from Target) worked about five minutes and then it quit working. I called Microsoft, got passed around multiple times, finally
Pros compact, good side button placement, travels well
Cons No side button on right side
Summary This mouse works on every thing from desk to table, even on a couch cushion, battery life is excellent!!
Pros nice mouse, good design, good response except on glass, i was happy while it worked.
Cons USB reviver stopped working after 2 months, computer couldn't recognize it any more and reviver got hot when inserted in computer
Summary if i had a lots of money and dint care if it will work 2 or 3 months i would buy it again, but i don't and i care so i bought Logitech .( it is not that Logitech is perfect bat that is for another rewiew )
