Pros: Looks different? Not a regular ordinary mouse. I guess that's about it.

Cons: Very awkward feeling to use. The thing/mouse is totally not sensitive. Won't move the direction that I want it to move. Don't know why I bought it. I'm always interested in new stuff.

Overall Review: Buy this to show off to your family or friends. It will be a good 1 day topic/conversation. But after that, prepare to put inside your closet or some place you store stuff that you never go to for years!!!
