YIANERM 3M Adhesive 4 Packs Thin Metal Plate For Magnetic Car Phone Holder (2 Round and 2 Rectangle)

Good quality sticking magnets. Hardly noticeable and work when placed 'inside' phone case so not visible outside

So far so good. Sticking just like the expensive carmount ones. Very pleased with my purchase

🧪 First Impressions Used these across two phones and a satnav setup—wanted something low-profile that sticks clean and holds firm. Straight out the pack, they’re thin, lightweight, and come with proper 3M adhesive backing. No peeling, no residue, and no bulk under a case. Stuck one rectangle plate inside a silicone case and one round plate directly on a backup phone—both held solid on a magnetic mount, even over bumps and motorway runs. No wobble, no drop. The magnets grip well, and the plates don’t interfere with wireless charging if placed low or off-centre. 🧰 Real-World Use ✅ Used in van and car—held firm on dash mounts and vent clips. ✅ Plates are thin enough to sit under most cases without bulging. ✅ Adhesive sticks clean—no lift after weeks of use. ✅ Ideal for phones, GPS units, or small tools with magnetic mounts. Also tested swapping cases—plate stayed put, no mess. Good for anyone who wants a clean, reliable mount setup without faff or bulky brackets. 👍 Pros ✅ Strong 3M adhesive—sticks clean, no residue ✅ Slim profile—fits under most cases ✅ Two shapes—round and rectangle for flexible placement ✅ Works with most magnetic mounts ✅ 4-pack—spares for multiple devices or setups 👎 Cons ❌ Not reusable—once stuck, it’s fixed ❌ Can interfere with wireless charging if placed dead centre ❌ No protective film included—watch for scratches on bare phones ❌ Not magnetic itself—relies on mount magnet 🧭 Final Verdict If you want slim, strong metal plates for magnetic phone mounts, the YIANERM 4-pack earns its spot. I’ve tested them across van runs, daily drives, and gear setups—no drama, just clean mounting and proper hold. Good stash-ready kit for anyone who wants their phone dialled without the faff.

Good products and good price. Very strong and attach great.

All good

Excellent item works very well and so easy to install on the phone case

The adhesive in these is very strong...sadly the magnets themselves are not as strong.

Wow one of the best products of this type , includes alcohol type wipe and cloth to wipe clear and dry and even a protective slip for phone Very impressive
