Secure Mount With Premium Feel
This phone mount feels incredibly sturdy once installed. No shaking or movement while driving, even on rough roads. The design looks clean and factory installed instead of bulky like a lot of other mounts. It holds the phone securely and keeps it easy to access for navigation.

Good Solid Mount
Got for my 2019 TRD Off Road. Works great, solid mount. Phone easy in, easy out once you get used to it. Looks and feels well made.

Solid Product
I was a bit skeptical based on the price ($85 total after taxes) but you can tell that for the price, this thing is sturdy and high quality. Holds solid onto the vent and keeps my iPhone in place. Easy to adjust and move to your liking, also easy to turn 90* and have your phone sideways. Only drawback is that is obstructs the view of the clock on my 4Runner and slightly obstructs my windshield, but I am sure I will get used to it.

Great phone holder
I use this phone mount in my Subaru Impreza, and it works perfectly with my vents. It holds my phone super securely—no wobbling or slipping—so it’s great for navigation or hands-free use. Really solid and reliable for the price.
