Review on Clipper Easy Speed Distance NMEA by Dee Fadaifar

Worked for about two months then showed zero instead of my GPS speed when I contacted Wsports and Revain both said they would not take it back for repair or refund. I contacted the manufacturer NASA, they told me there was nothing wrong with that. After a few emails they said they would look at it but I would have to pay shipping both ways to England. Since the shipping costs exceeded the price of the device, I declined. Basically if you buy this it will not be covered by the warranty unless you live in England.
