This a great little phone mount. It works for my iPhone 17 pro max. I drive a lot of dirt roads where I live in the mountains, and the magnet holds up to plenty of bumps without dropping my phone. Easy to install. Pros: -very simple installation -strong magnet -arm rotates for adjustment -ball and socket joint allows tilting with a good amount of resistance to hold its position (when fully tightened) Cons: - for model 3 users, anything other than next to the steering wheel can block a portion of your windshield viewing area -could have more modularity if offered with more arm attachments Conclusion: RECOMMENDED. Very stable and functional mount with a minimalistic design that still allows for some adjustability. If magnet weakens over time, or the sun damages the plastic to the point of breaking from brittleness then I will post updates. I will also update for any modifications I make for more adjustability.

This economical solution works perfectly
Color: Black
Very happy with this car mount. The magnet is plenty strong to securely hold my iPhone in its magnetic loop case. It’s plastic but it’s sturdy and fits on my Model 3’s screen perfectly. It has an adjustable height that I can mount my phone with full clearance of my steering wheel. Don’t waste your money on a metal mount, this inexpensive mount serves the need perfectly.

Good option for FSD drivers with a thin skin
Color: Black
Works great. Holds the phone very well and can be repositioned very quickly to accommodate various driving modes like laid back and deep or focus edge of your seat with getting yelled at by FSD (not really self driving)
