Mag-Safe Magnetic
Great product! The MagSafe compatibility is perfect—it snaps right on instantly. I prefer this over the wireless charging mounts because those always seem to overheat my phone on long trips. This is lightweight, stable, and the all-black aesthetic blends right into the Tesla screen frame. 10/10 for any Tesla owner.

Perfect Little Mount for Tesla Drivers
I like that this Tesla phone mount snaps onto the back of the screen cleanly and holds my iPhone with a strong MagSafe grip. It keeps the phone right where I need it without blocking the view, and the adjustable angle makes navigation super easy to see while driving. I do not like that it can wobble a tiny bit on rough roads, and the magnet isn’t as strong if you’re using a thicker case. Overall, a great accessory that makes the Model 3/Y setup even more convenient!

Tesla MagSafe mount for phone
Very cool phone mount that I hadn’t thought to purchase until I saw it as an option on Vine. Easy to install using the included adhesive strips pre-attached to the mount. It has a nice firm grip on the MagSafe for the phone and the mount itself sticks very well to the back of the Tesla screen with no issues. It is in the perfect location in the dashboard area as it doesn’t block any view or buttons. No negative aspects to my experience with this product.

Arm can be positioned in many ways, but doesn't grip as hard and the phone rattles in rough roads
I liked how this product looked in the picture so I ordered it. But when I installed it, I found out that it doesn't have the same amount of "grip power" because you have to turn a little knob on the side to tighten the grip and it's not that easy to do compared to other screw type phone mounts that have bigger screws. The magnet was slightly weaker than my existing phone holder but it was adequately strong. It was good to see how one could position the phone in different positions due to the way the arm is designed to be moved and adjusted. But the one biggest thing I didn't like is how the phone kept on shaking/rattling when I drove over rough roads. The metal arm is quite thin and although it's metal and not plastic, due to the thinness of the material, it was easily rattled and made the phone rattle a lot in return. Over smooth roads this won't be a big problem though. I wasn't quite satisfied with this, although it's adequately good enough.
