Title: I got two - both disfunctional
Review: I have two of these; they were OK when I got them, but one started to get "jerky" movement, and the other - well, just went bonkers.The jerky problem is well documented, just Google "VX Revolution jerky trouble". I've tried everything, many different mousepads, reloading software, cleaning the LED, all to no avail. After an embarrassingly long time, I finally gave up. It is REALLY picky about mousepad surfaces, but none worked acceptably.The other one has a weird sticky movement of the mouse wheel, but it isn't jerky. It does, however, open up 2 or 3 tabs at a time, and doesn't close them properly either, rendering it totally useless.I paid list price for these junkers.0 for 2 is not a good score.I can't recommend them, obviously.
Is the review positive or negative?
