Review on Ampper Strengthened Adhesive Upgrade Upgraded by Shane Black

Over the years I have bought them 6 times for 6 different cars. They couldn't be better, they're easy to set up and position, they never loosen enough to spin on their own or fall over (even at 110+F), and they give you a great view of your blind spot. no shriveled, tiny look like some fully round mirrors I've seen. The only problem is that they have to be repositioned after the car wash, but it's very easy. I can't imagine life without them - they offer an uninterrupted view of the car from the rear view mirror to those blind spot mirrors out your window with plenty of overlap so there's never a question of the car being next to you. I don't even use my normal outside mirrors anymore.
