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.

Best phone holder I have ever purchased!

Color: Dark Black, Size: 1 Pack

Hands down the best phone holder I have ever purchased. The ones that stick to the windshield always end up coming loose. This attached to your vent and is super sturdy. Very easy to install and uninstall without making a mess on your window.

Amazing Product!

Product worked great on some of the older trucks I use for construction vehicles. This product made all the lights look brand spanking new. Awesome product, and definitely recommend if you have any fogging in your headlights. It doesn’t matter the age of the cars/trucks as this product makes them look brand new regardless. I used on both new and older vehicles and you couldn’t tell the difference because the lights looked so clean on both. The product worked amazing . I also noticed at nighttime the headlights provided better visibility too! Perfectly priced!

This works

Wow!! I am shocked at how good this works. In addition to the fact that it works, it is Packaged with novice people in mind to get maximum results. This was worthy of before and after pictures; but, starting tge project, honestly didn't think it would result in the way it did.
