Super easy to set up
Style: Screen+Charger, Style: Screen+Charger
I couldn’t be happier with this car phone mount—it’s easily one of the best accessories I’ve added to my vehicle. The build quality feels solid and durable, with a strong grip that keeps my phone securely in place even on bumpy roads. Installation was quick and hassle-free, and it holds firmly without slipping or needing constant readjustment. What really stands out is how easy it is to use one-handed. I can mount or remove my phone in seconds, which makes a big difference while driving. The adjustable viewing angles are perfect for navigation, and it doesn’t block my view of the road at all.

Poor socket design.
Style: Holder+Dash+Vent+Windshield
Overall this is a pretty decent phone mount. I have used it with both the windshield and vent mounts. The only problem I have is the design of the ball swivel. The socket contains a rubber piece to help increase the grip, but over time heat from the sun or the air vent makes the ball glue itself to this rubber piece. When you try to make an adjustment, the ball will not move in the socket and ends up breaking the socket. This is happened to me twice.

Great Phone Holder
Style: Holder+Dash+Vent+Windshield
I bought the version with the suction cup mount and I’m very happy with it. It holds my phone securely in place and doesn’t move around while driving. It’s also very easy to place the phone in the holder and remove it when needed. The suction cup sticks well to the dashboard, and you can position it so the phone stays in a safe, easy-to-see spot while driving. Overall, a great and reliable phone mount. Highly recommend!

Best product and customer service around!!
One of the best car mounts I've ever bought! I love the mount’s powerful magnet, which ensures your phone stays locked in place even on bumpy roads, and the strong adhesive that sticks firmly to the back of the Tesla screen and holds it steadily. Plus, their customer service is off the charts. Very helpful and responsive.
