Does not have a suction cup. It is for the cup holder. Installed it in cup holder in 2019 Nissan Altima. Does not stay down in hole. The tighter I make it the more it pops out. When it is in holder with my iPhone XS Max plus, it bounces around while driving. What hoping it was better than my vent mount holder but not better. Probably worse.
Bounces around, won’t stay in cup holder.
