Pros: None since it does not work with Windows 7 64 bit

Cons: Sabrent's manual says that it may not work with the 64 bit version of Windows 7! And suggest reinstalling it which did not to resolve the code 10 message that the driver cannot start.

Overall Review: My chart plotting software for my Garmin MAPGPS78sc will only recognize COM 1 which is shown in device driver. I assume this means I do have a COM 1 port. So next I will will pull out my one year old PC from the desk and see if there is a serial port, in which case the problem will be solved and I wasted $15.00
