Works well, looks stupid with the logo display
This fits well in the vent frame and I am still able to close my vent. I really like the mount cause it solves a huge problem of where to put my phone securely... but I also hate it as well, because of the ugly logo on the face of it. "Batdiary"? Seriously? If I keep it I will look for a way to get rid of (or cover up) the extremely unattractive logo they selected. It makes it (and my trucks interior) look loke something for a child. I give it 5 stars because it deserves better than the 3.9 it had at the time of posting this. But for the love of everything clean and classy but still needing a mount, get rid of the bat logo!

Good, but minor issues
The build quality seemed impressive and it felt sturdy. When installed, it definitely stayed in the air vent without wiggling or coming loose after quite a bit of off roading and driving over washboards.
I returned this thing and bought the "off roam" competitor because of two reasons:
1) the ball joints don't tighten down hard enough to lock the position of the mount firmly. It grips well when you don't touch it, but if you are trying to put the phone into the mount without both hands, it shifts and moves with minimal pressure. Kind of annoying for me, I feel the ball joints should tighten enough not to budge if given a tiny bit of force or accidental bump.
2) the inner springs of the phone holder started loosening and making an obnoxious vibrating/rattling sound after about a month. Any bump or minor rough surface caused this thing to rattle like loose change in a cup holder IF THE PHONE WASNT IN IT. If the phone was in the holder it didn't do this at all. It started to drive me crazy.
If you can get past these two things it's built well enough and works perfectly fine. I just expect a bit more for $50-$60.
