Hi guys, I am reporting back with my new mouse, after using it for a bit I do think it is a very good product. It was very easy to get hooked up (just detect a Bluetooth mouse through the default system preferences). It has a really nice grip, feels good, and looks cool. As for battery life it's going to be a bit before I can tell you about that. Everything seems great, the one problem I have with the mouse is its accuracy when moving around at fast speeds. I personally use a very high sensitivity and when I slow down and try to do very detailed work (such as photoshop pixle by pixle work) I notice it doesn't have the accuracy I would like. However, it is still perfectally usable, just a new switch after using my logitech mouseman for so many years.
Overall I would suggest it, unless you have a problem with replacing batteries, which I will eventually have to do because it has no charger.
Let me know if you have any more questions.
