Top complaints
Ainope Drop-In Air Vent Mount (Gravity Phone Holder)
- Some break
Amazon's review summary says durability is a concern, with multiple owners reporting the mount breaking into pieces; stability is also mixed, from steady as a rock to wobbly.
- No landscape, no round vents
Because of the drop-in design it can't hold a phone horizontally, it doesn't fit circular vents, and you can't adjust the vent while it's installed (Wirecutter).
Source: Wirecutter (car phone mounts) - Thick or grippy cases can stick
The listing warns cases thicker than 14 mm may not fit, and Wirecutter found grippy-textured cases needed a little wiggling to release.

The USB-C power cable is almost 45 inches with no cable management, and the fan makes a faint whir that may be more noticeable in electric cars (Tom's Guide).
