      This won't let me down

      I had already used this product so I knew how good it was. Easy to fit to the windscreen. It wont fall off and is easy to remove (using the lever).

      Disappointed with the suction cup, will hold for a while then always keep falling off the windshield.

      Exactly what I wanted for my iPhone 11. Goes from the car to the jetski and can withstand off road and rough seas.
