volport Metal Plate for Magnetic Phone Holder Car Mount, Universal Ultra Thin Black Rectangle Metal Disc Replacement Kit with Super Strong 3M Adhesive Sticker, Sticky Magnets for Phone Case (69x52mm)

Filled enough of the phone case to allow for phone being any way up. Suitably thin. Held to holder magnet well - though that's partly down to your holder obvs. Worked for me. I'm pleased with them.

Just works as it should and good value and well packaged

Really like this product. The magnet is very big - a lot bigger than competitors. It's really strong. Previous magnets I tried didn;t hold my iphone pro max - this one hold it perfectly attached to my magnetic holder in the car

Yep they do and work well .

I usually dont write reviews but felt these far succeed expectations. I work for Amazon and usually main a certain work phone as i take care of them and put my own case/screen protector on them. With me getting a new case i need to buy new magnets as well and the magnets my work buys suck ngl so i needed to buy my own. Lo and behold i stumbled across these and wowww theyre great. Theyre pretty good sized, magnetic ability is insanely good, and the 3M tape on the back is crazy good. Ive had one on my work phone for a little over a year now and its not even close to coming off, still as secure as the day i put it on(work magnets fall off in about 2 months). Only thing is its started to get a little nicked and stuff but again, fully functional and still is on the phone holding to the car magnet. All in all for how much work abuse these magnets get (used everyday, on and off a car magnet about 300 times/day) they hold up extremely well, highly suggest!

Die Magnete halten was sie versprechen. Sie sind groß und halten dadurch besonders gut mein IPhone. Echt ein Top Produkt zu einem günstigen Preis.

Works well

Metallplatten hatten überhaupt keine Wirkung, viel zu wenig magnetische Kraft

I have a heavy smartphone, and two sportcars with sports (bouncy/reactive) suspensions. In one car, I've tuned the suspension down and the magnetic plate works fine. In my convertible? I'm having to constantly pick up the phone off the floor since the magnetic force is weak.So, I decided to try a larger attachment plate on my phone. Now I have to slide the phone off the magnet since it sticks so well. The plate itself is large, machined well with no warping or burrs, and the anodized black surface is smooth and non-glare. I have mine on the outside back of a phone case with a smooth plastic back so the adhesive sticks fine.If you have a heavier or larger smartphone (iPhone 12-13 Pro, Samsung S21-22 Ultra) you'll need a plate like this to grab at your magnetic mount... also be sure to spec one that can support the weight as well.
