Good product. It fits well on my Model Y screen. It worked fine for 3 months. but then the magnet became loose from the ring. I like the product so instead of discarding it thought of using glue to stick the magnet back to the ring. BUT it didn’t work. So now it has been a frustrating experience. I may choose to discard a product that has a strong mount, but the one important part (magnet) not working correctly.

works exactly as advertised. Tight fit, stable mount that doesn't allow the phone to move or fall out

The best Tesla phone mount

This is a great balance between effective "grabbing of the phone, visibility and a small mount that doesn't get in the way. The whole MagSafe mount sounds great in theory, but depending on the smoothness/slipperiness of the case the phone can bounce out of the mount, which is sub optimal for a variety of reasons. This gives your phone a stable platform while driving, is very durable and is very quick and easy to fit your phone into. It does a good job of attaching to the Tesla display without any messy adhesives and can be easily removed or repositioned without leaving residue. Highly recommended.
