Negative Positive
Title: not reliable
Review: I ordered this trackball to use with my laptop. I did not want to have all those wires etc when off site. I did not realize there is a base unit that needs to be connected, hence still wires etc. So I use on my home computer now. But it has stopped working for no reason, intermittently. I will put it aside and go back to my old mouse. Then, when I try it again, it will work, but for how long?Since I have had it less than a year (and probably was 6 months when I first had trouble) I thought to return it, but cannot find where to do this or how on Amazon...convenient?
Is the review positive or negative?
