Rotate & Lock Suction Cup Hook
This item easily attaches onto any non-porous, non-textured tile or glass surface without the use of tools or glue. Powered by our innovative suction technology, all you need to do is rotate the body of the suction cup clockwise until you hear a click and you're all set! With the sound of the "click", the suction cup creates a vacuum that will provide a secure hold. To uninstall, just rotate counter-clockwise and the suctioned air will be let go, freeing the product from the surface. Our suction cup is superior than other suction cups out there as it is made with the same components used in contact lenses and bulletproof windows. The average durability of our suction cup is 2~3 years whereas other suction cup based products need to be replaced within 6~12 months.
