Title: Ugh!!!!!
Review: As others have noted this mousepad is NOT optical mouse friendly---and really who has a trackball mouse anymore? For whatever technical reason the pointer suddenly jumps away and you then have to figure out where it is before scrolling back to what you were doing. If you have two duel monitors set up (as I do) your pointer often ends up somewhere in the other monitor (again, no idea why it does this) and your then scrolling around to try and find it. VERY frustrating. I wish I had kept the box so I could send it back.
Is the review positive or negative?
