I like that the install is very easy, non-permanent, and can be very quickly removed if needed. It fast charges and the magnets are strong (the reviews that say it doesn’t hold probably aren’t using a MagSafe case). That said I have two annoying issues: 1) There is a light that comes on when the car is turned on. If you don’t put your phone on the charger it will say on for a minute or two and then eventually turn off. 2) The included USB-C cable is too short. It only just barely reaches the outlet in the front bottom center console. It would be better if they had included a 6ft with a 90-deg connector to draw power from the back seat ports. 3) It doesn’t not include a charger. In all, the mount and charger are fine, but be prepared to spend an extra $20 on a longer cable and charger to make it all work.

Phone holder, not charger.

Nice plastic phone holder, works a lot better if you don’t have a phone case, it fits almost flushed. It doesn’t use “stickiness” to hold its self, just pressure from bottom phone, it holds nicely but has a little gap on the sides, it too much pressure is applied then Tesla screen starts showing pressure. The wire is small but reaches the under panel how ever, it does not fit flushed, will need to do some tinkering. I slide the wire under the charger where the phones go. Now the door can’t close but it can pass through. That charger is not fast but it works. Edit: nah, don’t get it. The charger doesn’t charge, it will charge them stop. It works like a phone holder…
