I bought this approx a month ago and have not been impressed by the vacuum seal. I wanted to use this for longer term storage for kitchen staples like flour, however the vacuum has released within approx 3 days. It is a good weight and feels solidly made but it doesn't hold a seal for long enough to be useful for storage. I have several of these storage containers and they are only good for very short term storage.

This is the one for flour, sugar, rice, etc. Holds a good amount and is very sturdy. Same quality as other products in the line. Takes up space, so some other sizes may be more practical than this one. I was able to convert to some smaller sizes and free up space in the pantry by not using as many of this size; only when they were the truly right size. I use the diffuser and top mounted label holder for this one because of what I store in them.

I bought several of these containers for dry goods I bake with. I have some in the freezer and some in the pantry. They work great and I recommend the gaskets for flour and fine ingredients. It ensures a proper seal for the vacuum. I highly recommend these.

These do not keep the vacuum seal. Especially if you use fine powder like flour, semolina, corn starch, etc. I've wiped the container and lid to get any stray dust off but I still have to re-vacuum this size container 3-4 times per day. The others work much better.

Its a great size. It keeps all my flours fresh. I love the app with the labels to keep track of freshness. Its easy to clean.
