Review: Great Magnet for holding phone in place while filming - I bought this for my phone which has a leather case so I can film myself while standing in front of a mirror. I paired it with a suction plate that also has magnets. This is a total game changer. Strong magnet, easy to apply and the adhesive so far stays in place. The quality is great and the magnet is very thin which is great so it does not weigh down my phone. Holds the phone very well in place and works well.
Review: Nice and thin but a strong magnet - I purchased these based on the reviews. They come in a pack of four: two round and two rectangular. I chose the round one. Easy to apply and thinner than the one I had on my old phone. I tried it out on my magnetized car cell phone stand and it works great. Would buy again.

## Questions & Answers

**Q: Does it stick well on silicone case or leather case?**
A: Silicone cases no it’s falls off after a few minutes, not too sure about leather. Hard plastic with no anti slip or straight to the back of the phone.

**Q: Will I still be able to wireless charge with this on the back?**
A: That's really depend on where is the spot of your phone provides the wireless feature vs where you are going to put the Metal Plate.  It will work as long as the Metal Plate don't block that spot directly.

**Q: How do I get a magnet for cell to stay on existing mount?**
A: Glad that you ask.  These are just Metal Plates.  These are not Magnet.  You need both to make the mechanism works.  Most Phone Car Holder / Phone Cases already come with the built-in Magnet which will automatically work with these Metal plates.  If you have any other questions, please let us know again.

**Q: Does this work well with outter box**
A: Sorry, we can't be 100% sure as the thickness of the phone case can be vary from one to the other.  Please be reminded that what we are selling here is just the Metal Plate FOR Magnetic Phone Holder.  Therefore, the item we are selling is not a magnet.  The strength of the magnet is all depending on its quality.  It's nothing much we can control.

To cut it short, our metal plates work for nearly all type of magnets.

Thanks,
Zhao

### ⭐⭐⭐⭐⭐ Nice and thin but a strong magnet
*by P***H on January 8, 2026*

I purchased these based on the reviews. They come in a pack of four: two round and two rectangular. I chose the round one. Easy to apply and thinner than the one I had on my old phone. I tried it out on my magnetized car cell phone stand and it works great. Would buy again.

### ⭐⭐⭐⭐⭐ Not only for phones
*by W***R on January 24, 2026*

These small plates are very thin and very strong. I actually used these underneath the cabinets above the bed in our RV. I stick small 3 speed fans with magnetic mounts to the metal plates. Works great to hold the small fans in place all night. Just remember, the plates themselves are not magnetic. They are only metal that magnets will stick to.
