We have ordered 3 of these for the office, two out of three are not working properly. When I called customer support I could hardly hear the representative and after I gave her the S# and P# she could not pull up the script that she was supposed to read to help me fix the issues. She said there was no info on it. I gave her the numbers right off the mouse. The issue is that the mouse lags, when it is working it has a quick pace (that is adjustable in the settings), but if it is not working the pointer will freeze and it is too frustrating to use. It only works for a few minutes and then freezes up. The solution that I found on HP's site (that the HP representative could not find) is not very convenient. I had already tried most of what they suggest. They ask for the receiver to be one foot away from the device. How feasible is that on a desktop at an office? No way would I recommend this mouse.
