Works well on 2003 Corvette.
Color: Carbon Fiber, Size: 2 Pack
I purchased these for usage in my 2003 Corvette convertible. As much as I enjoy the vehicle, they are extremely insufficient for storage. No "usable" built-in cup holder, no pockets and no flat area that can hold a cell phone. The console and glove box are not ideal in this day and age since the phones are used constantly. Enter these excellent little holders. They mount perfectly on the central vent in the dash. If you slide the bases as far as possible to each side and then tighten them down, the base will overlap the non-moving portion of the vent and keep the unit quite stable. I would suspect this is applicable for any vehicle that has the traditional flat vent fins. The holder has a hook that when fished into the vent, clasps over the back of one of the fins. By hooking the fin, once tightened down (careful not to over due this as the vents are just plastic) the installation is as stable as you can ask for vs any of those goofy clamp types that slide off quite easily, especially as they age and sun softens the pads. Benefit from my mistakes on those bad purchases and stay away from clamp mounts. If you have flat fin vents and are looking for a reliable means to mount a phone, this may be just right for you.
Best of luck.

Good product, but...
Color: Dark Black, Size: 1 Pack
Easy to install. Like the product. The holder does not hold the phone position. It flops down alot.

The Perfect Phone Mount.
Color: Dark Black, Size: 1 Pack
It’s the perfect size, easy to install, and works perfectly. I have a 15 pro max iPhone, and it fits perfectly.

Well built and removes cleanly.
Color: Dark Black, Size: 1 Pack
Seems to be very solid and it was a little bit tricky to get it located on the vent blade properly, though that might just be due to the vents shape in my Highlander. I really like that it can be easily moved from one vehicle to another if needed without leaving adhesive residue like my last mount did. The only concern I have is whether the vent blade will support the weight long term. Time will tell I guess.
EDIT: This fits all of the vents on my 2011 Highlander great. On my 2022 Highlander it will only attach to the center vents and then just barely hooks on after angling the vent blades enough for the hooks to grab. Even then the mount only makes contact at the very top and bottom of the vent opening. It works, but I wouldn't recommend it as ideal.
