I have had these for three years. Only issue I had oddly enough was the wiring harness went bad about three months ago. After troubleshooting with Technostalgia they sent me a new one no questions asked! Great product and great ppl. Install is fast and easy if you remove the rear clip. Three screws, one bolt on each side, unplug it and the whole rear clip pops off. Very easy. Took me about an hour.
