I love them! They work very well so far - I have had them for maybe 2 years and the lids still work well and hold a seal. The only thing I do not like about them is that the bigger ones I use for flour are somewhat hard to handle getting off the shelf because they are heavy when filled and the sides are completely smooth,so there is nothing to grip, making it a two handed job. Not that big of a deal.
