The best!
Size: Gravity, Color: Black
Probably the best, most functional, most adaptable (to different cars, going on #3), longest lasting car mount I've tried. Getting another one for my 16 year old who is about to start drinking.

I couldn't be more happy with this thing.It's been with me for a couple years now.And it's so sturdy, it gets tightened when loose, and it's easy to remove for cleaning
