MOSUO 9 Pack Metal Plates for All Magnetic Car Phone Holder

They started falling off after about a month. And they were stuck to a clean formica type surface which they really should have adhered to properly.Also magnets seem to lack strength on them: the same magnets I use on a magnetic board, don't work well on these discs. I think this is partially because they are so smooth with no natural friction, but also because there is too little metal content.Used as a phone disc, the phone slips off the car magnet mount easily.So, to sum up, they are really not thick enough, are too smooth, do not have enough metal content for magnets to bind to, and the glue is also weak.Original discs that I've received with previous phone holders have been way better.

They are thin but very sturdy, They attracts to a magnet very well.Surface is shiny silver metal, not blue as many reviews says. Protective film is light blue as you can see on photos.They come with 3M adhesive which has very strong adhesion but the thing is that when you stick it you need to leave it for about 24h before usage

stuck this on to a spignen case on my Oneplus 8 pro.I was concerned that it would stop me using the wireless charging but i put it right at the bottom of the case and it still worked fineI use a mpow magnetic holder in the car and it works really well

These are excellent. Credit where it's due. These come with a thin adhesive film which you can apply to a surface you don't want damaged (such as the back of your phone) and then you stick the metal plate on top of that with its already applied 3m tape. I wasn't sure how this would work and couldn't understand how the metal plate would adhere better to the phone than the film underneath, but it's solid, unobtrusive and holds well to the dashboard magnet. I've had other plates like this that don't stick well at all.

No chance in the world this is M3 adhesive. This thing fell off within 5 minutes. When I put my finger on the adhesive it is clear that this is no good, it has no adhesion whatsoever. Or these have been lying in the sun or whatever, but they are rubbish.

Bought these to extend the use of a magnetic holder fitted to my car's dashboard. In use, straightforward, just stick to the back of your device and that's it! It depends on the quality & strength of the magnetic holder as to what can be connected but I have fitted a 10" tablet using one of these discs and so far, no issues, even over quite bumpy roads.

Very poor quality glue on sticky pad. Fell off within a few hours. Thought they were blue at first but that’s a very fine plastic coating. Not decided if it’s a waste of money yet, may buy some double sided tape and try again.

These magnets did just the job for my existing mobile phone holder in my car. The old one was stuck on the back of the old phone cover. Plenty left over as spares or to pass on to anyone that needs them.
