Perfect Phone Mount: Secure, Versatile, and Easy to Install!
This phone mount has truly exceeded my expectations! It’s incredibly easy to install and holds my phone securely in place, providing total peace of mind while driving. What really sets this mount apart is its impressive versatility—I've never seen anything quite like it. The base attaches firmly to the air vent, and the adjustable arm allows me to position my phone precisely where I want it, with the freedom to tilt it up, down, left, or right. Plus, it doesn’t interfere with air flow from the AC, which is a huge bonus. Although my wife's phone case isn't MagSafe-compatible, the included metal ring works seamlessly with it, and my MagSafe case connects just as smoothly. I couldn’t recommend this product more—it’s been an absolute game-changer for us! This is a personal purchase, and I’m thrilled with it. I’ll be sure to update if anything changes.

Secure and great fit
I gave this product a chance and it did not disappoint! I did not need to read any instructions for installation and was able to quickly and easily figure it out. Installation takes less than 5 minutes. Just align the mount to the top corner of your tesla screen and turn the dial to adjust the tightness. Once tightness is set, just test to see if it’s really fitted by wiggling it around to check for looseness. I like the fact that I can adjust the angles of the mount easily. My phone can be angles to be on top or side of the Tesla screen. When driving, my phone does not shake one bit. When it’s time to remove my phone, just give it a quick pull to detach and that’s it. The build quality is also very nice and I like the design of it overall. I think it’s a well thought out product. Definitely would recommend to friends and family with Teslas.

Good mount but…
This is a solid mount for the Tesla monitor but the mounting points on the corner of screen caused my screen protector to bubble up. I had to return it unfortunately.

Tesla 😋😉 jeep phone mount.
Bought this to go in my jeep, perfectly attached to the corner of the screen of the screen, the only down side is since my screen raises and lowers over time with the vibration of the jeep it does make the screen slide down. But the magnet holds the phone very well as long as it is aligned properly to the back of the phone. I know it say tesla mount but my choice of smart stereo for my jeep is not a flush mount, it sticks out and has a cd player in the deck. As well the screen raises and lowers for access to to the cd player. So perfect for my jeep.

Amazing MagSafe phone stand
I recently purchased this MagSafe car phone mount, and it has been a game-changer for my daily commutes. The installation was effortless—just snap it onto the air vent, and you’re good to go. What stands out the most is the strong MagSafe connection. My phone stays securely in place even on bumpy roads, and removing it is just as seamless. The minimalist design fits perfectly with my car’s interior, and it doesn’t block my view like other bulkier mounts. Another highlight is the 360-degree rotation feature, which makes adjusting the angle for navigation or hands-free calls incredibly easy. It’s sturdy, reliable, and eliminates the need for clamps or adhesives. Overall, this is a must-have for anyone who uses their phone for GPS or music while driving. Highly recommended for MagSafe-compatible phones!
