Magsafe car mount for a Tesla screen that is easy to adjust and holds the phone very well
Style: MagSafe Car Phone Holder, Style: MagSafe Car Phone Holder
I installed this mount on my 2018 Tesla Model 3 main display and it was easy to install - just loosen the wheels on the top and side clamp, put it in place and then tighten the clamps back down. There is a ball mount on the back which tightens as well that allows you to position and angle the phone mount so you can tilt it up or down or towards the driver. You can adjust the phone on the mount to where you want it - although the bar that holds the phone will hit the clamps in two spots so there are a couple of positions that don't work due to the design, but overall you can more or less put the phone where you want and and then tilt it any which way to you. The magnet connection is very firm but the phone also detaches relatively easily. The clamps so far are holding well on the screen. I really don't have a lot of complaints - except maybe that there's a couple of positions that don't work. It works well, installs quickly and easily and seems to hold well in use. I've had no problems so ar.

Mostly reliable to use
Style: MagSafe Car Phone Holder
It's nice to use in my car to separate out different needs like looking up a specific route while moving and the navigation is going somewhere. The magnet is pretty strong and haven't had any issues with that. However, if you dont put it in the corner of the screen to secure it at a right angle, the flat way to secure it in the middle of the top edge is not reliable at all. The weight of the phone and the angle of the mount makes it really easy to fall off the screen no matter how tight you secure it down. Fell at least a handful of times. Just put it at the corners and you'll be just fine.

Does not fit the Cybertruck. Will slip off due to angled backplate.
Style: MagSafe Car Phone Holder, Style: MagSafe Car Phone Holder
It does not fit the Cybertruck well. Due to the angled monitor back, it will slide off. Check the video of what I mean. It is not flat like the Model 3 or Ys. The mount should work fine on the Model 3 and Model Y and Newer Model S and X, but not on the Cybertruck and older vertical screen Model S and X. The Magsafe that I received must of been broken. It completely fell apart. Everytime I put on phone on it, the Magsafe will completely come off stuck to my phone.
