Hi Guys, I'm looking to buy a new Bluetooth mouse for my macbook. I have been using the bluetooth mighty mouse, but i'm quite unhappy with it. The scroll ball keeps getting dirty and it stops working every week, and i have to clean it to get it back to work again (And I do wash my hands very often!) Also, I find that the resolution is very bad, and sometimes find myself struggling to click where i'm supposed to. My idea is to get a mouse which is Bluetooth has good battery life laser if possible to improve resolution has a charging base I had a radtech bt600 before but it was not good, and had to return it. thanks in advance for any help.
