I originally bought Kensington’s standard trackball but quickly rejected it as there was no scroll function. This new one has, but after some use I now find that the supplied wrist rest is the best thing about it as my wrist rests on it perfectly and as this model comes with two buttons each side it is much better ergonomically. Because of this - and quite perversely- I seldom need to use the scroll function. I am very happy with this deluxe version - apart from the price which is ridiculously high.

Kensington Expert trackball. I'm an engineer and find this unit badly designed, badly made and over priced for something made like this. The scroll wheel has a lot of play and wobbles all over the place. The bottons are not ergonomicly in the right place. I will sell this and buy another brand as I'm not impressed.
