Smooth, strong, impeccable. reposition to get it just right if you are careful and keep it clean.
super solid. I really love the articulation this offeres. So much flexibility. Iphones natively may be limited in using the full potential of the wattage due to internal limitations on non apple wireless pads, but I'm pretty sure this is faster than the tesla chargers by a lot. the build quality and modern vibe are impeccable.

A great line of sight phone holder with a few flaws.
Overall this does the job and is priced affordably the pros and cons are as follows:
Pros:
Strong magnet
Solid construction
Great for line of sight
Charges well
Cons:
Charging cable is not long enough to route inside my car
holder tends to droop down slightly with my phone on it (Pixel 7), not so much that it's failing but just not holding it's set position

Does not swivel and slow charger
As mentioned in another review, you cannot change the angle of the phone so it faces the other way since it does not swivel. Wish I wish I would have known that before placing it. Also, the charger is REALLY slow. It’s slower than the MagSafe chargers I have in my house. I’m not sure if this is defective. I only used it on my way home from work, and I will be returning it.

Tesla Phone Mount for Magsafe: Tesla Car Phone Holder for Tesla Model 3/Y
Okay so I received this Kaisepoch Tesla MagSafe phone mount, compatible with Model 3/Y, through Vine for review, and this is one of those Tesla accessories that’s all about convenience and clean in-car phone positioning. First impression—it’s a MagSafe-style magnetic phone holder designed specifically for Tesla Model 3 and Model Y interiors, so the idea is that it mounts neatly without cluttering the dash and keeps your phone visible for navigation or quick access. In general, Tesla MagSafe mounts like this are designed around either screen-edge or dash-mounted positioning depending on the generation of the vehicle, with magnetic alignment for one-hand docking and removal.
What I like:
MagSafe magnetic attachment makes it quick to dock and remove the phone
Designed specifically for Tesla Model 3/Y interior fitment
Keeps phone in a visible navigation-friendly position
Cleaner setup compared to bulky universal mounts
One-hand operation is convenient while driving
Things to know: Fit can vary slightly depending on Tesla model year/interior generation; Magnetic strength depends heavily on your MagSafe case quality; Placement matters—some positions may affect screen visibility depending on preference; Like most Tesla mounts, long-term stability can depend on heat and surface conditions.
Overall, this is a clean, simple MagSafe Tesla mount option that focuses on easy phone access and minimal clutter. If you want a straightforward mount for navigation and quick phone docking without overcomplicating the setup, this is a solid pick.
