Review on Doubletake Mirror Indestructible Motorcycle Mirrors by Jason Bellman

So far the mirrors have worked very well. I haven't had a chance to test their indestructibility yet, so I can't comment on this feature. Therefore, I rate the durability as average. I replace original BMW mirrors that broke when I dropped my bike at low speed. Since these mirrors can move on impact I don't think they will break. The 8mm bushings had to be drilled and cut to fit the 10mm bushings. Threaded part of the base of the mirror. Extra 8mm. Bases would be nice if you didn't have the tools to drill and tap.
