Summary: This mouse did not work. I had a computer smart neighbor look at it and he concurred. I guess I should have known that a cheap mouse was not the one to buy. I went out locally and bought another one.
Summary: AVOID BUYING THIS ITEM until the instructions are rewritten! I bought this mouse for the specific purpose of having it as a wireless device and a wired device, just in case the batteries ran out and I wanted to keep using it. I sent it back after three attempts to get it to work on three different computers. The instructions, which are so poorly written, give you NO CHANCE of making this mouse work, unless you guess your way by trying possible connections.
