0/10 chance it’ll actually hold your phone
Instillation- easy. Function- terrible, it didn’t hold my phone up for more than 2 seconds before the entire holder fell down (IPhone 16 pro; 7.5oz with a slim case.) Fit- great but useless for the durability.

Not Worth it
This mount was great for about a week. After that it popped off and would not stay in place. I would not recommend buying this.

Waste of Money
Worked great for about a week and then came off. It won’t clip back on now.
