Bests & Worsts Reviews from Amazon

I don't know why this has so many 5 star reviews because they aren't durable at all. The plastic seal is removable and fall off easy which is incredibly annoying and just more pieces I have to make sure don't get lost. Now after just one use and not even ran through the dishwasher all the plastic seals are breaking making them not air tight and useless for what I need them for.
