Not a good buy
Straight up, this thing is horrible. Doesn’t hold on to anything; especially if you add your phone, it just drops, damaging your screen. Don’t buy. Had no grip whatsoever or adjustability.

Does not hold as advertised
Color: Black
When the dash got hot from the sun, the glue gave way and everything ended up on the floor. Couldn’t send it back because the time limit had passed but I don’t use it
