I have an SOS transciever. Did not make it through its warranty period before it stopped recieving signals. Took it back to the dealer where I was given a form with a phone number to call. For a warranty claim I had to send it to Canada, pay shipping both ways, and give them a credit card # so I could be charged if they determined I was somehow at fault. In retrospect, after the loss of use for half the winter, getting stuck with shipping costs, long distance phone charges, and the time spent hasseling with the post office I should have pitched it in the dumpster and bought a Tracker to replace it. Anyone else have warranty issues?
