I have three koomus CD slot magnetic phone holders. I recently upgraded to the Samsung S9 using an OtterBox defender case. I placed the metal plate between the plastic case and rubber shell. Unfortunately, the koomas plate interferes with the wireless charging for the phone. Im not sure if a rectangular hole in the plate would help allow the phone to charge, but if you plan on using these plates, it will not allow you to charge wirelessly.

These are great! Much better quality than any other mounting plate and I have purchased several trying to get the best. I got this as an add on item which saved me 50%.

Nice firm hold on my cell phone.

I love using these metal plates rather than the ones that comes with my magnet mounts. Since these seems to have a thicker metal place, whatever magnet I used, it would take a better hold with the magnet. I WOULD RECOMMEND THESE! Plan to buy more to replace all of my other metal plates. Only downside is that since they are a little thicker, they might not slip inside a case like some are supposed to do. So I use the adhesive that comes with the plates and they are strong and reliable.

Holds great to the magnet, the magnet unit is another story

Great magnets, no issue here.
