I have been looking for a good reason to buy a set of the Doubletake Mirrors for my RX3 and have just found the greatest reason of all. I lost the reflector on the freeway a few days ago and it was run over by 50 cars before I could loop back around to try and save it. My wife and I have both had problems with the backing on the reflectors getting loose and the reflectors hanging out by a small piece of the foam sticky tape but have never lost one completely. I ordered two sets of the Doubletakes and they should arrive today from here.

Warranty statement on the Doubletake Mirrors: it is made right here in Colorado Springs from a super tough nylon that we are so certain will survive we offer a lifetime warranty (on the housing, not the glass, but you can buy the glass seperately), and sure enough, it folds right down when you want it gone.
Here is the picture of the missing reflector on my right mirror. Sorry for the fingerprints I just ate fried chicken.
