This is a nice unit. It is small and can be mounted just about anywhere. It is a good large display that is easily visible in the daytime or the dark. Simple hookup as well, just a matter of plugging it in.My issue is that it is not very accurate. At slower speeds it is closer to on point, but at highway speeds it is 5 to 6 mph too high. Kind of defeated the purpose for my use.

This instrument works, but it's difficult to use and awkward to mount inside the car without some kind of bracket or mounting platform. It's also difficult to change from one measuring system (miles) to another (km). It definitely cannot be done on the fly. For safety sake, park in a safe place before adjusting anything on this particular gizmo. The power lead is very long - that's nice.
