I think you will regret quadlock sturdiness and longevity. I do not believe Fidlock elastic band or suction will last for years (beside the fact I do not know if it is good for the phone to have a big magnetic field so close). But have to say quadlock is not so sturdy too, the case soon develops cracks in the fixing hole; there was a period I was replacing the cases now I bet the little cracks will stay this way forever giving the phone the little movement needed to "support" vibrations
Use fidlock for 1 1/2 years now no problem with the system I m very happy how it works and how easy I can access my phone and get it back on when on the ride …
@@cycling2adventure im using quadlock right now and i agree with your problems with them, the mounting system after a while is less annoying but still a hassle, peak designs out front looks great but its out of stock eventually ill swap to that I think
