Best suction of any screen car phone holder recommended buy

Most useless bit of kit Samsung ever produced. It falls down all the time no matter.how often I clean the glass. It has gone under my foot while driving a few times almost caused an accident when I couldn't press down on the brake, now I have gotten a fine for touching my phone to check Google maps while driving because it was sitting in my cup holder. Piece of rubbish (would use harsher words but that wid give them.an excuse to sensor)

I purchased this dock thinking because it is a genuine Samsung product it would be the best, it continually falls of the windscreen even without a phone in it so I tried using the mounting disk adhered to the dash board and again it appeared to stay on with suction and then fell an hour latter. I tried cleaning the windscreen with pure alcohol , still fell off then sprayed the suction cup with water and it still fell. Considering the price and reputation of Samsung I'm very disappointed.
