"Very good portable mouse"3.5 starson by urr_quasdim
Pros: (1) Smooth scrolling (after latest software update)
(2) Light and portable
(3) Easy to use (after short learning period)
Cons: (1) Takes some time to master the right-click feature without scrolling away from target
(2) Should be less expensive
Summary: Not a gimmick IMHO but a useful, highly portable mouse. Once installed, an update is prompted, resulting in real smooth scrolling. After a short learning curve it's easy and fun to use. Price is a bit steep though.
