I've been purchasing the universal adapter for five years for different phones. They are great.

Got for my old phone case and it worked great. I dont think it will ever come off because of how sticky the backing is which is nice cause i didnt have to worry about it falling off while riding.

I will not use any other phone or electronic holding products. Quad Lock is the only ones I trust to protect my electronics. Weather it’s on the bike, but n my work truck or in my POV. They are simply the best.
