Yep, they're right. 100% correct...These lids don't seal at all! Buyer beware. Don't assume that just because it has the Rubbermaid name (which is usually a good choice), that it is a good product. It isn't. Markedly below what I have come to expect from Rubbermaid. And I can't return it because I got this container and then didn't use it for about 2 months. Oh well...at least I didn't pay that much.
