Cons: Usually it does not work at all. Problems include, poor out of spec USB extension cable which comes packaged with device which leads to the device losing connection constantly. Cheap materials leading to a poor overall feel. won't even show up as a mouse on many computers.
Pros: I really liked this mouse but two days ago my pc started to freak out! I thought I had a virus attacking my USB ports,nope just a cheap intermitent cable! You would think you could get more than two months for a brand new product. :(
Cons: $20 or two months! Lets see if I can get a replacement or my money back...
Pros: Nice retractable cord. Small size is easy to transport and store. Seems to work just fine.
Cons: This puppy is small, with a capital "S". The cord and mouse do not fit into the included tote bag very well. The cord does seem to be a mite fragile, but it is holding up pretty well so far. Mostly very minor cons.
