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.

Surprisingly good
Size: Gravity, Color: Deep Space Grey
I bought a very old Lexus as a second backup car and as such, it doesn't have any of the amenities we are used to. This phone holder is surprisingly smartly designed. Every time I put my phone in it I'm impressed that it holds it in place.
