5 Stars with 1 Call-Out….
SOLID built like a tank! Really like the all-metal design. No vibration on the road and minimal if any off road, extremely stable. 360 adjustability = endless options on positioning your phone. Overall a good buy considering fit, form and functionality as compared to the less expensive composite holders that shake move and rattle (Drives me nuts). The ONLY negative…. I have a pro max iphone with a case and there’s no way one-handed operation works to insert and remove the phone into the holder. You can use one hand to adjust the angle and positioning but not otherwise. An OFI for OffRoam, incorporate a tension adjustment into the design for ease of insertion and removal of the phone (without breaking the bank). Taking all things into consideration the pros far outweigh the cons! Best unit out there for Gen 3 Tacoma owners.

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.

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.
