Smartphones Metal Plate 12 Pack for Phone Car Mount Holder Cradle with 3M Adhesive (Compatible with Magnetic Mounts) - 6 Rectangle and 6 Round, Black

Nice and strong magnets that work well on my cell phone! Keeps my phone on my car mount even through bumps and rough terrain! Hasn't fallen off yet! Definitely recommend!

I purchased these magnets for the back of my phone. Best purchase ever. I have plenty so if I want to trade phone cases in the future. For the price, strength, and look of these magnets I will purchase them every time I need new! They work well. Easy to install. And perfect sizes! All around win!

I like that these magnets come in 2 different size and shape. I used the larger one on the back of my samsung 23 and had no issue with installation to the phone and it had a good strength to my existing car mount (checked it on that before placing on phone). These magnets are not too thick I used my under my phone case they are strong but thin enough for you to cut into the size you need. If you wondering if these will work as a diy craft refrigerator magnet no they wont, they don't stick, i tried. Happy with Quality, Price, and Quantity.

Easy to apply metal plates for magnetic use

It works beautiful upon my needs…. Excellent choice

I've used these things on the biggest phones on the market. I used it with my Samsung Z4 Fold and the Galaxy 25 Ultra (with a battery case).These are two heavy, unwieldy phones that most phone mounts cannot handle. The magnet strength is excellent and I never had a the phone drop while using these. They're strong enough to hold a tablet, if you wanted to.

Item is exactly as described. 6 rectangle flat metal plates and 6 round flat metal plates all with adhesive on one side. It holds strong to all my magnetic mounts. I have this on the back of my iPad and it holds very sturdy to the small magnetic mount I have for it. If placed inside a protective case to hide the metal plate it doesn’t have a strong magnetic hold. Even with a thin layer between the metal plate and the magnet it’s sturdiness is decreased drastically. My phone still holds to the magnet with the plate inside my case but falls off easily if moved or bumped. It’s only works best if the metal plate is able to directly touch the magnet so if you have a nice case you don’t want to ruin covered by this then I wouldn’t recommend buying this. The adhesive is very sticky and strong. Not easy to remove once adhered to item so be sure it’s exactly where you want it. Not meant for sticking and unsticking for reuse on different items and not meant for readjusting. Although possible to remove and reuse again it will without a doubt lose stickiness quickly and removing after stuck risks damaging the item you stuck it to or ruining the adhesive on the metal.

Perfect to replace my old one
