Super Powerful Vacuum Suction Cup Hook Holder,Organizer for Bath Ball, Towel & Clothes(Pack of 2, Chrome)

The idea and design is excellent and they are sturdy. Unfortunately, they do not stay attached. I took them on a month long trip to Europe to attach my "clothes line" to the walls of showers and bathtubs. They grip initially, but release after a very short period of time (less than an hour).

Only 1 of these stuck. The other 1 keeps falling off!! Wouldn't buy!!

worked really well for me. I'm on my third order.
