Get the stubby, not the standard
This is a very nice mount. I strongly recommend the stubby version over the standard, mostly because you can move the phone holder around to help keep it visible and out of the way. As a taller guy, the standard mount would be hitting my knee when I get in the vehicle, but the stubby mount allows me to move it further towards the passenger side, which also keeps my cup holder usable.

Perfect fit attachment!
This product is built very strong and fits perfectly into the small cubby in the lower middle dash of my 2018 4Runner. It holds my iphone tightly but is easy to remove. 100% satisfied with this purchase.
