Suction not strong enough at all.....
this is supposed to be the accessory for the "main Squeeze cup" but the suction of this cup can not hold it (the main squeeze cup does have some weight..) even on a very clean glass surface. it just keep falls down. waste of money...!
Definatley recommend for hands free fun.
I found it great for adding an extra edge to my main squeeze fun. Sticks most surfaces, just set at ideal height and your away.
Do have some issues with the suction cup coming off, usually takes 2-3 goes for full suction, but once on no issues
