Excellent product.
First impression: excellent product. The only reason I deducted a star is because the price is obviously quite insane.

A+ mount for 4Runners
This is the best phone mount I've ever had. Got it for my 2021 4Runner. Very strong, doesn't come loose, easy to place and remove the phone from the mount. Can't recommend enough.

Best Phone Mount EVER!
I searched the Toyota forums and consistently saw this item mentioned as one that would not move on bump roads or even over time on smooth roads. It is the best and must secure mount I have ever used. It fits perfectly on was designed not to obscure the view. I have recommended this brand to everyone that I have talked to about mounts since I got. Very easy to install also!

The fit is perfect and is a sold mounting system
Custom fit for 2022 Tacoma, fit exactly. Very sturdy mount and took seconds to install. All metal with the exception of a adjustment knob. Quality hardware. More expensive than a lot of mounts but most are cheap plastic and are not nearly as solid and sturdy as the Offroam.
