Review on 📱 6 Pack Metal Plate for Car Phone Magnetic Mount - Replacement Disc Sticker with 3M Adhesive for iPhone, Magnets Cradle-less Mounts, Cell Phone Stand, Mini Tablet, GPS - Includes 2 Rectangular and 4 Circular Plates by Jose Haskin

I like the tin design and you get a good number for a good price. Unfortunately I found that the glue wasn't strong enough. The first one I tried broke immediately and just didn't work. Sure, I just popped it in, but the magnetic plate I got with the mount worked just as well. Nevertheless, I followed the instructions more closely and made a second attempt. I pressed the second plate against the back of the phone for a good 20 seconds and it worked. First. But unfortunately it broke even after only a few days of use. I ended up having to order replacement plates from the original manufacturer of the mount.
