We've got a glass kitchen table and the glass weighs about 150lbs. It sits on top of this elaborate designed table base. Even though the glass seems to seal pretty well, there always manages to be some cat hair, dust, or wayward gnat that finds itself under the glass. Every time we have to clean it, it's a very unnerving task of having to pry the glass up and clean underneath it. I constantly have visions of the glass splintering into a thousand shards, cutting us into ribbons. Being able to now put the suction cup on one side and lift is a game changer. This is going to make our cleaning chores THAT much easier. Honestly speaking, if you look at this suction cup, how it's designed and how they built it, it seems very under priced to me.....just sayin'.
