The concept is great, but it’s uncomfortable when you use it just with 1 finger, it pokes the inside of your finger. And if you want to slide your finger in, you need to squiggle your finger into it. Also wonder how long it will last before breaking.
The magnet held very well, however, when I tried to take off the ring to be able to put my phone on my charger. Since it won't charge with my wireless charger, the plastic and ring part fell out. Leaving me just with a center magnet.
First, it does lay flat against your case, and it does stick well, but that’s about it. The “loop” is not for men with normal size hands. If you can’t use the loop, you can slide it between two fingers. But you have to may sure it’s rotated and oriented in such a way that you can do so. Also, the mechanism that expands is thin plastic that cuts into your fingers. Mine is now on the box and in a drawer of other bad purchases.
