These containers are fantastic! I have been using them since they came out (which was probably 10 years or so ago now). I have containers from this line in all shapes and sizes and they have all held up really well-no breaking, the seals still work great, dishwasher safe (though you never want to put the lids in the dishwasher and always clean them by hand because water gets into the lid otherwise and it takes forever to dry). The only thing that might be seen as a negative for some is that flour and other fine particle storage items can make the lids not seal right so they won't be airtight for those types of things. It's just because fine powders get on the seal over time and makes it so they can't grip the interior walls of the container as well as they would with something like cereal or cookies. If you are battling pantry pests and need something really airtight for flour, cocoa, or baking soda for instance, I would suggest going with a snapware type product that doesn't have interior seals. Otherwise they are very functional and they look sharp in the pantry.
