The bracket comes with only one metal ring to attach to a phone. I tried my with a metal plate that was already on my phone case and because of the specific design of the bracket it wouldn't stick to the magnet. In other words it likely will only work with the included metal ring. That"s fine, if you are the only person using the phone bracket. In my case, we are two people who use the car and would require 2 metal rings for both of us to use the product. If I could purchase or obtain an additional ring that would be a plus and wouls have resulted in a higher review.

its good, the retaining knob won't stay on so I used a nut.
