Great product, great for the delivery drivers out there
Color: BLUE
If you are debating about getting this dash mount, get it. I haven't fully tested the wireless charging but I have a pretty uneven surface and it sticks extremely well, the holders that hold the phone are electronic and they sense whether or not the phone is in there once open so it won't just close randomly. If you turn the car off, you can release it, go away for a few minutes and then come back, set the phone on there, and turn the car back on, and after a few seconds it will clamp. If you press the button while the car is off it will clamp as well. I would recommend testing whether or not it wireless charges on whatever one you get, just in case of a defect, and you don't even need to take the film off to test it. This one is one hundred percent worth the money..

Color: Black
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.
