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

Seriously, great magnetic plates

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.

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

Smaller than expected, definitely smaller than my mounting system. Because my phone is heavy and these magnets are small, it falls from the mounting system. I recommend getting a bigger size magnet. I have an iphone xs max, so its heavy. However, they do stick well so im sure it will work with regular size phones.

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.

A great product to do exactly as intended. I was able to use these discs to use a replacement phone case on my iPhone 13 mini.

I don’t know if I got a bad batch or if my magnetic car holder is too strong for theseFirst I tried them on my siliconeized case cover & as soon as I set it on the phone holder it pulled it right off in a heartbeat.So then I removed my case and stuck it directly to the backside of the phone itself & it stayed for about a minute and then the magnet pulled it right off as well.And on each attempt I used an alcohol wipe to make sure it was clean & would adhere well. Not the case here, they just don’t stick strong enough to anything, other than the magnet and the get stick inside the rubber lip are a PITA to get out & off! No matter how I do it. And theonly way to get the disc off the magnet privy it up with a pocket knife & by the time you’re done it’s bent and unusable. These are the same disc size that the original one I had & those lasted stuck in place forever.Either way I’m retuning these & trying someone else's metal discs. Or finding a different style of magnetic ball holder. Or a whole different type of holder all together.

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.
