Review on Piutouyar Suction Sucker Window Kitchen by Jason Wright

Everything but the suction cup itself is great in this product. The physical cup is undersized with a cavity that is too shallow and a plastic connection that is too rigid. Will not work on powder coated surfaces or other surfaces such as plastic that are not highly polished. Works well on smooth flat glass. It sucks well as long as it's not disturbed. Once you apply lateral force, it will fall off immediately (except for pure flat glass, plastic, which will fall off immediately), direct pull is ok. If you're considering keeping the product since you bought it, stick with stainless steel. Any defects in the steel and they do not stick because the plastic does not form irregularities except for a mirror finish. So again, they're perfect if you don't want to glue them to anything. Ah, a riddle.
