Amazing iphone mount for Model Y.
Color: Upgraded Version - Gray
I was pleasantly surprised at how this phone mount worked for my purpose. I am a care driver and drive a Tesla Model Y. This mount perfectly fit the screen and my iphone doesn't come off even when I hit a pothole. The best part of this mount is the price. One cannot find anything cheaper than this. As for the function, this mount really fits the bill. Thumbs up!

Decent MagSafe phone mount
This was just an average MagSafe. Build quality is ok. The material, especially the plastic parts, feel cheap. The design is nothing to brag about. It can be mounted anywhere along the edge of the screen. Although it's marketed as for the Telsa Model 3/Y, It can be used with any cars with a tablet that fit's the dimension. I actually had problems installing it because I have a screen protector on and the added thickness resulting it the mount barely being able to squeeze it. Note the design prevents adjustments in certain mount positions as the end of the slider will run up against the lock nut. Magnetic strength is acceptable although I question the stability when the slider is at it's maximum extension with a phone mounted. Overall, it's perfectly functional but I would prefer something a bit more refined and minimalist.

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.
