I've used fancier Kensington's in the past. But their software ("Mouseworks") can't be beat, and the mice have five-year warranties that actually are honored by the company. Smooth movement, ergonomic shape, unbeatable software. I highly recommend Kensington pointing devices. My husband has used their trackball for years and it just keeps trucking. Daly
