Sturdy and well built
This Tesla phone mount has a sleek minimalist design that blends nicely with the interior of the Model 3 and Model Y. The foldable hidden style keeps the dashboard looking clean, and the strong magnetic hold keeps the phone secure even during turns or bumps. The 360-degree adjustment also makes it easy to position the phone exactly where you want it.
The mount feels sturdy and well-built, and the MagSafe compatibility makes attaching and removing the phone very convenient. It works well for navigation, music control, or hands-free calls without blocking too much of the screen or airflow. The compact design also helps it look more like a factory accessory rather than an aftermarket add-on.
Overall, this is a stylish and practical Tesla accessory that combines strong magnetic support with a clean modern appearance.

Minimalist Design with Premium Match for Tesla Interior
This MagSafe phone mount features a highly minimalist design, but the build quality is excellent and it performs perfectly. The installation process was incredibly straightforward and hassle-free.
Key Highlights:
Strong Magnetic Hold: The N52 magnets are exceptionally strong, keeping the phone securely in place without any slipping.
Perfect Color Matching: I purchased the gray version, and the color matches the gray backing/trim of the Tesla central screen almost exactly. It blends in seamlessly as if it were an original factory accessory.
Discreet and Functional: It does its job efficiently without adding unnecessary clutter to the dashboard.
Overall, I am highly satisfied with this purchase.
Pros:
Seamless Integration: Gray finish pairs perfectly with the Tesla screen housing.
Powerful N52 Magnets: Provides a stable hold even on rough roads.
Clean Aesthetics: Minimalist, foldable design that can be hidden when not in use.
Cons:
None—excellent value and functionality.

Excellent MagSafe magnetic phone holder
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
