I think the touch pad is too small, you need to move a few strokes to get the cursor to the position you want. I tried to adjust the cursor speed, it helps a little but not much. Battery get drained off already after 1 month of use.Worst of all, there is intermittent problem, sometimes the keys (happened most frequently with the number pad) does not work. That is, nothing came out when you type, might need to press the key a few times then it resume.I wonder if I can return this keyboard? It is not cheap, and the problem comes and go. After switching to other keyboard and tested for a while, I am sure now that there is problem of the wireless keyboard.
