Question: Is there a little triangle at the bottom of the container indicating #2 or #5 plastic? I think only #2 and #5 are both food safe and safe for reuse.
Document: I now have 2 of these - one for regular flour and another for bread flour. All the Progressive containers are great and fit into my red kitchen. This container is great because it fits a bag of flour perfectly (you may have to pack the flour a little) and the built-in leveler is genius!! I make bread every few days and this makes it easier to measure out flour in a flash. The plastic is BPA free and feels sturdy, like it will last.
I'm confused this product is made with recycle number 7 plastics/other. I heard to stay away from these plastics because they may contain BPA.I know this product says its BPA free tested but really wanted to make sure. Its one of the main reasons I bought this product. I want something safe for my family but when I opened up my package today and saw recycle number 7 on the bottom I was very disappointed. Other than that the container is nicely made and fit my cabinets perfectly.
This is a sturdy well built container. The cover and hinge seem solid - and I did not have a hard time opening it. I have granite counter tops though and it does slide a bit on them (especially when flour gets on them which makes it even more slippery!). The little do-dad that helps you measure is o.k. but it gets a bit in the way when I'm in my groove.I did not see dishwasher safe anywhere on it so I hand wash.
Getting right to the point- I love this container. It has a great seal, it's dishwasher safe, it's skinny yet holds 5 lbs of flour, and the leveler is totally convenient. The leveler is not removable, but I don't really mind. Having the leveler there helps keep flour messes to a minimum and helps you get accurate measurements. I definitely am going to look into Progressive's other ingredient keepers. HIGHLY recommended!
Pro - I really like the built-in levelerPro - hinge seems well made and substantial.Con - Built-in leveler and cover are not removable, making it hard to clean.Con- Not air tight. I filled with soapy water to clean it and it leaked from between the container and the latched closed cover.Container does not feel sturdy, it feels like it would break easily. Bottom line - overpriced piece of plastic.
It does hold 5# of flour; however you cannot use the leveler until it is about 1/2 empty. 5# of flour fills the container to the top.I had this item washed and thrown away the paper that came with it, so I cannot return it. So I will use it until I find something better.It is too pricey for the value, in my opinion.
The width of this container allows me to use a full 1 cup measuring cup without any hassles. Which is FANTASTIC! No more using a measuring cup with a broken handle or a 1/2 cup to measure all  my bread flour! I appreciate the width, sturdiness and lid of this container.However, it really does just fit your 5 pound bag of flower. READ: You cannot use the built in leveler until you have removed approximately four cups of flour.
The only reason it didn't get 5 stars is because the leveler isn't removal and so it makes it a little hard to work. However it is the perfect container for keeping my Bisquick. I can see when I need more, and it stores neatly with a tight fitting lid. Nearly a five star purchase
I was expecting something a little bigger, not having read the product description closely and buying all my flour at Costco in 20 pound bags, but the size turned out work quite well. The container seems to be of a nice and sturdy construction, no cheap parts. I really liked the leveler, since baking is supposed to be an exact science it is nice to have that little tool. The container easily fit the 5 pounds of flour it claimed, so that was nice too.
I ordered this to store my flour. It has a built-in leveler which is very handy when you are stirring something with one hand and need flour. I liked this product so much that I ordered the same thing to store my sugar and 2 small ones for baking soda and a slightly larger one for brown sugar. I saw the small containers at a kitchen store and looked at the bottom to check that it was made by Progressive.
Answer: Avoid using #7 plastics as much as possible-it is a mixed bag and you never quite know what kind of plastic is included in the mix. i have emailed this company asking them to explain to me how it can be bpa free and still be a number 7, waiting for the reply.
