It holds the phone pretty well!
Updated review: I gave this another try and it worked, the reason was previously I was rotating the nob in the wrong direction... now it fits pretty well and stays in the installed position securely! But I'm still worried about the added pressure on the display, hopefully it works fine. Overall I think it's worth a try if you need a magnetic phone holder! (ps: I was never contacted by the manufacture, I figured out the correct way to use it so I came here to update my review) --- Original title: Doesn't fit my Model 3 display too well, and it adds pressure on it. I wouldn't recommend it Original review: I don't understand all the positive reviews of this MagSafe holder. It could work, but I find it very unstable on my Model 3 2023's display. After I fit it onto the display and tried adjusting the angles or taking off the phone, the holder tended to fall off. Also it adds pressure to the display which could technically damage it. I wouldn't recommend this.

not holding up well
It was a great idea and kinda worked for few weeks.. but every time I have to jiggle a bit to get my phone off from magnet or try to adjust the angle, the whole system comes off.. and now all the supporting sponges came off.. I tried to fix and reuse but didn't last at all.. it comes off too easily from the car monitor.

So Much Worth It!
This phone holder works so well! It is sturdy and hold on pretty tight. Very easy to put the phone on and off the holder. It even protects the screen so well with the little corner protection foam! Five out of five stars!
