Sturdy and secure
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!

Good product.
This works well. It's sturdy and holds the phone well. It does keep the vent from adjusting but not a big deal.
