Pros: After years of use, decided to replace with the same model since it served me so well. I'm as pleased with the new one as I was with its predecessor. This one appears to have a battery saver which is a bonus. Touching the scroll wheel activates the mouse giving me more battery life before replacement/charge without resorting to actually turning off the mouse with its switch.

Cons: None!

Overall Review: Two thumbs up! There are very similar models from Kensington which differ in size to suit a smaller hand. Not a bad idea to try one on for size before purchase. I heartily recommend this mouse.
