Review title: Eats batteries, trackball has very jerky motion...not a quality product.
Product review: I bought one of these for use in my lab at work. Even though it is not used every day, the keyboard requires new batteries every 2 months or so. The "spent" batteries measure barely below the nominal voltage, i.e. they are usable in other gadgets. But for some reason the keyboard can't use them.I have never been happy with the trackball performance, since day one...it is jerky and very frustrating to use.I am looking for a replacement for this product.
