Suction cup: Highest quality, American made suction cup. Thicker cross sections to hold longer and stronger. Superior USA-sourced materials and manufacturing. UV-Stablized to resist yellowing and fading. High clarity PVC phthalate-free material for a refined, professional look.
IF OUR SUCTION CUP DOESNT WORK ON YOUR SURFACE, NO SUCTION CUPS WILL. If the product falls off your surface, you cant use products with suction cups. Like any suction cup, it works best with non-porous surfaces. Will not work on porous stone such as travertine. It will last forever on glass, mirror, and smooth tile. However, surfaces like brushed stainless steel/copper and some plastic shower surrounds, are actually slightly porous. On these slightly porous surfaces, the suction only lasts for a few hours to a day. Plenty long enough to have your drink in the shower, but it will not stay for weeks like truly non-porous surfaces. This is true for all suction cups, even though ours is the highest quality and rated at 7 lbs strength. A separate adhesive disc can be purchased for installation on nearly any surface.
Strength depends on application. Apply to dry surfaces only- wet surfaces with condensation should be dried first. A tiny lick on the suction cup sometimes increases strength, depending on the surface. Please test the application before use, and always use SipCaddy responsibly. Not intended for use with glass vessels.
