Pros: Easy to program, clear, large screen, quick loads

Cons: none yet

Overall Review: Saved me over an hour in traffic delay by G.W. Bridge. I'm hooked. Took me through in 5 minutes

Pros: nice when it worked

Cons: Lost power after 4 months. DO NOT waste even 9.99 on this mouse. This was an extra mouse ,not even heavy workload. 2nd Rosewill mouse to burn out after very light use.
