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.

Worked in 5th gen Forester
Size: Gravity, Color: Black
This phone cradle worked well in my 2019 Subaru Forester which has kinda tough air vents to connect a cradle. I'm really glad this worked because I tried a couple others without success.
