Feeling Fancy!
Color: Black
This is one of the best purchases I have ever made in my entire life! I never bought one of these because of the blocking of air vent, but this one totally does not block ac vent, fits perfectly, it adjusts a lot, it tilts towards me, up, down, to the passenger, it can go from landscape to portrait stance, moves up and down, and hooks on super well to the vent. Material feels good and sturdy!! It is good for my needs! Also, the clamping part is a little strange to get used to when squeezing it down to clamp in my phone however the phone has not fallen off! I love it! I freaking love it! It makes using my phone easy to use and the installation was super easy as well! Feels made of good quality material too! Would make great for a gift!

Awesome Vent Mount That Actually Stays Put
Color: Black
These vent clips are awesome. Setup was fast and easy, and it holds the phone very securely without bouncing around while driving. I also like that it has a 360° adjustment so you can get the angle right, and it doesn’t block the airflow like a lot of other vent mounts. Overall, it works great and does exactly what it’s supposed to.

Great attachment and sturdy
Color: Black
This item is great! The mount to the vent is secure.
The only issue I have is when I want to move the arm to a different position, you have to unscrew the mount, and sometimes it comes undone and I have to attach to the vent again once I get it in the correct position. It could be because of my narrow vent though.
It also jiggles a little on bumpy roads, but that is to be expected with something that extends so far.
I like that the part that holds the phone doesn't cover the camera, so I can actually take a photo of the road with it.
I would definitely recommend and/or buy this again.

Buy it! You won't regret it!
Color: Black
I was unsure of this holder since I live in the mountains, and drive on rough roads daily. This is by far the best phone holder I have used! It self adjusts on the bumpy roads, but thats expected. On city roads, it works perfectly! My phone is on the larger side, and it holds its weight just fine.
