Title: Better than previous models
Review: I have used trackballs for years and really like them. You can't beat the way Kensington will stand behind them with a 5 year warranty. The scroll rings could be smoother. Does not seem to just move small amounts but jumps in increments. I do like the ring as far as where it is located. Many ways to set up your buttons and controls. I did not need the wireless model and so saved money with the wired one. Amazon had the best price when I purchased mine.
