Fits under the car seat screw. It's the perfect length and while it's a little wobbly that's to be expected as the length is again perfect. I use it to hold my iPhone 7 Plus and I can easily mount it both horizontally and vertically. Also, it doesn't bother the passenger, which is good. I chose a cup holder mount as my cup holders are too far back for me to see my phone without turning my head. This mount keeps my phone in the perfect position while driving.
