Pros: Fantastic little scanner, best price/performance I could find for a 2D matrix capable barcode scanner. Has excellent range, speed, configurability.
Cons: I initially had difficulty getting the 123Scan2 software to work with Windows 7 64-bit but then discovered there is a slightly newer beta version. Downloaded it (almost 400MB!) and then everything worked like a charm! I enabled some extra settings and was successfully scanning UID tags in no time.
