Review on 👁️ 2" Oval Convex Stick-On Rear View Blind Spot Mirror with REAL Glass, Aluminum Housing - Rust Resistant, WIDE ANGLE - Suitable for Motorcycle, ATV, Boat, Car, SUV - Say Goodbye to Blind Spots by Derek Davie

I installed them on the new Toyota 4runner according to the instructions. I rubbed the glass with rubbing alcohol and dried thoroughly to make sure the glue stuck. The first day the passenger side fell off while driving on the freeway. When I got home, I tugged at the remaining one and it fell out of my hand very easily. It wouldn't have taken long if I hadn't done anything. So I used a razor blade, loosened the original adhesive on the back and replaced it with the 3M tape I have. He won't fall again. My advice to anyone buying this junk is to get rid of the supplied adhesive immediately and replace it with something that will keep them from falling off.
