Summary: nice rechargeable wireless mouse -- easy to install and use and don't have to replace batteries. Would have been nice to include NIMH rechargeables with the package at this price, but overall works great!
Pros: Wow. I bought a wireless Microsoft Blue mouse about 6 months ago. I returned it. Then i bought this sweet thing and it totally Owns microsoft. It has perfect reponse and is good if you play online games where u need extreme precision. Definetly an awesome
Cons: expensive but with rebates and everything the price isn't that bad
