🧪 First ImpressionsUsed 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 VerdictIf 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.

Perfect for the job !

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

They’re decent for something affordable! I use these in my car for hands free (obvs don’t recommend) but it’s good for when I need maps as I can stick my phone to the magnet

Work well very strong
