The indoor positioning beacon is what you can use to track the position of the beacon, or any object the beacon is mounted on with an accuracy of up to 2cm.

Good looks that betray a flawed locking mechanism
Style: Charging MagSafe Mount
I wanted to love the Spigen TapLock—its sleek design and promise of a secure, easy-to-use latch mechanism had me hopeful. At first, it felt solid, and the concept of a spin-to-lock system was clever. But after just a few weeks, the latch mechanism started failing. It wouldn’t adhere properly anymore, and the spin-to-lock feature became completely non-functional—no amount of spinning tightens the lock. Fixing it? Near impossible. The design buries the mechanism in a way that makes repairs a nightmare, and there’s no clear way to realign or replace parts without breaking it further. It’s a shame because the build quality isn’t terrible otherwise, but this critical flaw tanks it. One star—looks good, works briefly, then betrays you. The charge speed is pretty good.

Good product
Style: Charging MagSafe Mount
Great product. It allows my iPhone 15 pro to sit at the right angle so that it is not completely behind steering wheel. I like that it doesn’t use a glue base to secure to monitor. I have taken It off 3 times and it went back on well. The only negative I can find is that it’s a little bouncy or I should say more than I would like it to. I would recommend to a friend.

So so. Could be great with few improvements
Style: Charging MagSafe Mount
Overall, this mount is decent with good functionality and quality but a few things (short permanently affixed wire, no way to stow/hide, fixed arm length) make it annoyingly fall short of great. (Phone S24+, TPU case, ESR "magsafe" metal ring sticker)
GREAT: Arm rotation (i.e. portrait/left to landscape/top) is super easy with one hand via a simple push of a button that clicks into position every 45 degrees. Great design unique to this model. Most others require a cumbersome loosening and retightening mechanism that is difficult with one hand and tedious to position where wanted.
GOOD: Build quality. Secure and reliable attachment to screen without adhesive. Reliable wireless charging. Pad swivel/tilt is easy while staying tight and secure without any nut/screw to loosen. Includes attractive velcro (for carpet) and adhesive (for plastic) wire routing clips.
SOSO: Magnet could be stronger to support phones (like mine) with a simple metal ring vs a fully magnetized magsafe insert - still holds strong enough while driving tho. No way to stow/hide the mount when not in use - no folding hinge - the pad bumps against the display when rotating down, so it won't rotate behind - no folding hinge either. Arm length not adjustable - my S24+ is positioned nicely as-is but larger phones may cover the Tesla display and smaller phones may be too far away from it.
BAD: Wire too short to completely hide behind dash and under floor mat. Made worse by a permanently attached wire at the mount. Would be much better if attached via usbc, so it could be replaced with longer wire.
NOTE: If a screen protector is installed on the Tesla display, this will cause it to bubble around the clamped edges.

Very well designed mount but loosens over time
Style: Charging MagSafe Mount
Works amazing but over time the mount loosens up and the phone sags or rotates on its own. There is no way to tighten it more - only the part that connects to the Tesla display.

Great phone mount for Tesla.
Style: Charging MagSafe Mount
Firstly, I love that it is fastened to display via a turn knob. The previous product I had was attached by adhesive and in the summer it would fall off. Which is the reason I purchased this product.
I also love the ability to adjust the arm so mount the phone whichever way you'd like.
