We purchased two pair of these in 2021 to secure the awing of our side tent to our teardrop. Solid hold even in stiff winds and steady rains. They worked as advertised; for about three years. Now they will not maintain suction on the smooth surface of a teardrop.
Keep them clean! There are no care or storage instructions. I affixed the clear discs to the suction cup after each use to ensure no debris would get on the suction cups. For the price they are not bad. But, if you are camping/RV’ing , carry spares and be prepared to replace every few yrs.
