The other reviewer may have had RF interference, if two wireless mice didn't work for him. I have had no problems so far, and this works much more reliably than my last one. Precision is good with the laser, and it 'wakes up' quickly (less than a second) after sitting for a while. Side buttons are a little hard to get to with my hands being on the larger side, but I don't often use them anyway. I let my wife try it when her Mac mouse was going bad, and she loved it. I'll probably buy her one as well.
