Good option for FSD drivers with a thin skin
Color: Black
Works great. Holds the phone very well and can be repositioned very quickly to accommodate various driving modes like laid back and deep or focus edge of your seat with getting yelled at by FSD (not really self driving)

'A Must Buy'....!!
Color: Black
I have had multiple Magnetic phone mounts, this is by far the best one yet. For the price, it is a 'must' buy, it fits perfectly on corner of screen, very tight, never an issue with bumpy roads, sharp curves, etc. You can use mount at different angles, whatever suits your needs.
