It doesn't use "suction", it fits in a cup holder, then adjust for a snug fit. When inserted and tightened, it will not move. I use it in a Honda Fit with a Samsung Galaxy S9. The phone is tight, I can easily adjust the angle of the phone. The neck is adjustable to tilt it. The fit is not quite optimal, it could be a bit higher so as not to be in the way. But actually it's pretty cute.
