'A Must Buy'....!!
Color: Black
I have had multiple Magnetic phone mounts, this is by far the best one yet. For the price, it is a 'must' buy, it fits perfectly on corner of screen, very tight, never an issue with bumpy roads, sharp curves, etc. You can use mount at different angles, whatever suits your needs.

Nice Phone mount
Great phone mount—stable, easy to use, and gets the job done! I’ve been using this phone mount for a few weeks now, and it’s exceeded my expectations. It holds my phone securely, even on bumpy roads, and the adjustable arm makes it super easy to get the right angle. Installation was a breeze—took less than 2 minutes. The grip is strong without scratching the phone, and it feels sturdy overall. Highly recommend if you’re looking for a reliable mount!

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.
