Negative Positive
Title: Very poor motion
Review: I had a Kensington trackball a while ago and since I am always on the computer, I thought it would be a good idea to get another one. I like the quick launch buttons which save a lot of time when you use the same programs a lot. The scroll button is not in the best place since you have to reach up over the top to get to it. My biggest complaint about this is that the tracking is horrible. My mouse pointer skips around all over the screen which makes it difficult to work with. I tried everything described for this problem at Kensinton support, but it didn't work. I probably would have been much better off with the non-wireless model. I would send it back, but I don't have the box anymore.
Is the review positive or negative?
