Have been wanting these for a while, and they are truly a dream! They make our open shelving look so neat and organized and now we have a better idea of what food we actually have. I love the function of the vacuum seals and they thus far have been keeping our food nice and fresh. I would say the only possible con is that we need more of the larger containers than the smaller ones, but we can always buy those a la carte. I would HIGHLY recommend this set as a great start/introduction to the OXO pop series.
