My first Reverb Stealth gave me no problems whatsoever in 3 years of riding, until it failed spectacularly (although that was the fault of the installer). My current Reverb, which is the newly redesigned version, started having slight movement almost immediately. It has not gotten worse in the 8 months since, and it does not really bother me. If it fails, I will probably replace it with the Bike Yoke. I have heard nothing but good things about that one.
