Mount itself great, holder is meeehhh
4/5: One star removed because the holder comes off the mount VERY easily, and phone is difficult to make small adjustments to while driving because of the placement.
The mount itself fits very well in my 2014 FR-S. Super easy to install, no hassles. I used this to replace a "seat rail arm" mount, so it's very different from what I'm used to. The phone is very far out of reach, which is almost certainly safer in concept but if you do decide to futz with something it's much more dangerous. Just get everything setup before you pull away, or pull over for a second.
The only problem I have is the QBA45 is very "meh." I have a Nexus 6P in a Spigen slim form case which a rubberized/grippy back. Whenever I drop my phone in the mount, it ALWAYS sticks when I pull it back out. It sticks hard enough that the holder comes off the mount.
I'm likely going to look for another holder that happens to fit well.
