It took a few tries to get it positioned exactly as i wanted it but once that was done it hasn't moved. I have a Samsung s25fe phone with a case and it fits just fine. Seems secure. It does shake slightly while driving on bumpy roads but it doesn't move positions and I don't feel like my phone is going to fall. So far it's been great.

Quality cell phone mount.

The best cell phone mount I ever used. Quality is obvious after you easily install. This hasn’t moved since I placed it in my car. I like that it doesn’t block the air vent too. (You can move any angle you like). Won’t disappoint! Good buy!
