Happy Bell (12 Pack) Mini Mount Metal Plate with Adhesive for Collapsible Grip & Magnetic Phone Car Mount Holder Cradle (Compatible with Magnetic Mounts),Black

Only ones I could find that would fit inside the circle of a magsafe case to mount my phone to the magnet in my car

Seriously, great magnetic plates

These disc adhere to surfaces well and look nice. Just what I needed for my project.

Will not hold my phone to the fridge but it does hold it to my car magnet so I’m happy

I bought these to use with battery powered automatic LED lights. The lights came with an adhesive strip and had a magnet attached so they could be attached to a steel surface. The problem is that to attach them to a non-steel surface one would need to use the double-stick adhesive pad. Then to change the batteries one would have to tear off the adhesive. I used these to attach to the wood surface and use the light's magnet to attach to the disk. Works great! The adhesive is plenty strong to hold the lights and it is easy to replace batteries now.

Plate attaches to my magnetic dash mount as expected but kept sliding off my silicone iPhone case. Bought a separate set of 3m “stickier” stickers to fix the issue. Sucks it wasn’t a one stop fix (and cost more money) for the mount issues with the iPhone 12 Pro Max. Got there eventually but a lot of wasted money in the meantime. Do like the plain matte finish though.

Fits my Samsung Galaxy S23 Ultra in a Spigen case perfectly and does not interfere with wireless charging like the larger mounting disks do. This smaller disk has plenty of surface area to stick securely to my magnetic mount.

I was hoping they would fit inside the finger ring and still have it be functional. They are too big for that, so my rings are now permanently flat. But the magnet mount is a higher priority for me, so I'm happy with these.
