My mother had rubbermaid cups and plasticware from I want to say when rubbermaid first started out as a company. So, naturally following in my mum's footsteps I bought rubbermaid. I have probably the full set and this set is just to add on to my growing rubbermaid warehouse I have going on in my cupboards. I'm so happy that all the lids and containers stack together otherwise it'd be a mess!! These containers I know will last me a LONG while and shipping was incredibly fast!!Pros:Dishwasher, microwave, and freezer safe....this plasticware can do it all!!Easy to clean out, all the nooks and crannies are easy to cleanLids snap shut on their companion containersHaven't had a leak yet!!Cons:None thus far!!Overall a great purchase and one that I was extremely happy to make
