OWLKELA Mount Metal Plate for Phone Magnet Car Mount Holder Cradle with Adhesive, Universal Replacement Sticker Compatible with Magnetic Mounts - 10 Pack Silver (4 Rectangle and 6 Round)

These have great adhesive. I used a square one to patch a crack in a laptop cover. Sizes are as described.

Peel the paper backing off and apply to case or phone and you'll be how surprised at how firmly your electronics stay in place...

These come with plenty of different options! They work very well. If your phone case is dirty it may not adhere very well. Make sure you take off the plastic on both sides!! At first it’s hard to tell but there is plastic on both sides. Does NOT stick to rubber/silicon phone cases

I like the silver-colored ones-they can double as a mirror if you need to check for food in your teeth, or apply lipstick or whatever so that's a plus. I stuck one on the back of my phone, which has a semi rigid clear plastic case on the back. The plate seemed to stick well until I attached it to my magnetic car mount and when I pulled my phone off the mount, the plate came off the back of the phone. So I took some sandpaper and made the spot where the plate goes on the plastic case a little rough and then wiped it with an alcohol pad. I stuck the other silver plate on and so far it seems to stick better. So far, it's stayed on the case with no issues. I don't want to attach the plate directly to my expensive phone which is why I stuck it on the case.

I purchased a new to me car with a magnetic phone holder that was left in the car by the previous owner. A little research determined that all I needed to make the holder work is a metal plate. Found these and have been very happy. I chose not to stick it to my phone, so I cannot comment on the quality of the adhesive. That being said, the plate works perfectly placed on the inside of my phone’s case. The magnetic hold might be stronger without the case, but I think it is just fine without it.

Product works like it’s meant to received today placed them on my phones, I’ve bought these before and they worked I just need to stop getting new cases lol but decided to share with the fam so the 10 pack came in handy.

They don't stay on the windows at all, there are no additional fasteners

The plates stay where you put them. I use them for more than just car and phone. I am using them around the outside of the house to hold up LED magnetic lights. So far anyway. Great product.

Like the color and works great

Funcionan perfectamente y van debajo de la funda o pegada con el pegamento que trae.

Muy buen tamaño para celulares y otros dispositivos y en este caso lo más importante es que el imán de mi camioneta lo agarro perfectamente y con fuerza, viene con cinta doble cara 3M el cual es de muy buena calidad. Recomendable relación preció calidad. Además que en mi caso llegó mucho antes de lo indicado.

Mi spiace dover dire che, sarò stata sfortunata, ma mi sono ritrovata con delle piastrine metalliche praticamente inutili, ben lontane dal fare ciò che "promettono": l'adesivo non ha tenuta, niente proprio, e non regge il peso di un telefono con aggancio magnetico, men che meno di telefono più ulteriore supporto/magnete di rinforzo (forse riesco a usarne un paio aggiungendo abbondante nastro adesivo ai lati, sicché...); il lato metallico suppongo vada bene per attaccare piccole calamite da frigorifero, appuntare fogli... non so di che metallo sia, ma la resa è davvero minima. Personalmente, sconsiglio l'acquisto.
