I’ve been using this magsafe mount in my car and I’m extremely impressed with how well it works. The installation was simple, and once it’s on, it doesn’t move at all. The magnet is strong enough to hold my phone securely even when I’m driving over bumps or taking sharp turns. I also really like how clean and minimal the design is — it blends in perfectly with the interior without looking bulky or distracting. My phone snaps on instantly and stays centered, making it easy to see navigation without blocking the screen. Overall, this has been one of the best accessories I’ve added to my car. Reliable, sturdy, and very well-designed. Highly recommend for any car owner looking for a solid magsafe mounting solution. Doesn’t necessarily have to be just for a Tesla!

Solid phone holder

This tesla magsafe phone holder was easy to install and works well, its compatible with any tesla and the magsafe magnetic ring is very strong and secure to my phone, and im pretty happy with that, it also is pretty adjustable so I can angle it so I can see it better, and overall is a great addition to any tesla. I do wish that the part connecting to the back of the screen to mount it was removable, because the only way to mount it is with the included adhesive and I didn't like that so much The build quality feels great and is well made. Overall though if you dont mind the adhesive mount its a great magsafe phone holder for teslas

Almost perfect

Style: Screen+Charger

Solid mount. I’ve tried other ones but they don’t sit as nicely as this one. It also has a lot of adjustments to allow for using it any way you need it to so it is very versatile. The magnet strength is really good and holds my phone really well. Sometimes it feels too strong which I guess is a good thing. The charging works well but I wish the cable was a little longer

Almost Perfect But With Workaround it Rocks

Style: Dash+Screen+Qi2 Charger, Style: Dash+Screen+Qi2 Charger

This works almost perfectly in my Tesla, with one small tweak for hot summer conditions. It holds my phone very well overall—I position it slightly off-center at about the 10 o’clock position. However, with a larger phone like the Galaxy S25 Ultra, the combination of weight and summer heat can cause the mount to slowly rotate as the suction cup loses some grip. I found a simple fix that works extremely well: applying a small amount of rosin (the same kind used for violin bows) to the friction point where the rotating arm meets the suction base. That added grip completely solved the issue. Now the mount stays exactly where I position it, even in the heat. Solid product, and with that minor adjustment, it performs exactly how I need it to.
