Query: Saved me time and frustration

My husband bought me the original set more than two years ago as a surprise gift, after seeing how much time and frustration I experienced every night after dinner trying to find the right lids for all the food storage containers. I admit I was skeptical of an "as seen on TV" product but I have been very very pleased! I save time and frustration because every container takes the same size lid, and because they are so neatly stacked together. The containers have held up very well--I did crack a couple of them when full and frozen. I also have a very high-end dishwasher (came with the house) that melts nearly everything plastic but the containers do fine in it. I believe it warped a couple of the lids since they don't fit as well now. So I handwash the lids now. I am purchasing the expansion pack to replace those few pieces which didn't make it past the two-year mark. For the money, this is an excellent product that I will continue to use and buy!
