Ordered 3... All 3 are duds!
This mouse is comfortable to use and connects to your computer quickly, but otherwise, all 3 that i ordered went into the trash! I ordered 2 at first, one for my home computer and one for my office, and one of those would lose signal with my computer, and i'd have to pull out the usb receiver and pull out the batteries for it to pick up the signal again. At the time, the other one didn't have this issue so i assumed it was a fluke, and i ordered another one. That one ended up having the same issue, but not as often so i decided to live with it. Now the other of the first two that i ordered keeps jumping around the screen, especially when i try to highlight text or select a large group of cells. I switched the mouses between computers and the issue persists, which indicates it's the mouse. This one is going in the trash too. What a waste!
