Your Website is VERY confusing. You list what a product is made if but don’t list what’s a safe level. And you don’t test the made in USA Tupperware for instance. I was looking for Made in USA results. Plus I heard you say that Brown Tupperware had nothing bad in it but couldn’t find it to read about it. & You haven’t completed Testing all the colors in Pyrex So it’s a hit & miss whether we we can use any of it. Solid straight forward info on Tupperware from u is badly needed. The PopScience.com says Tupperware is safe. So you’ve conterdicted them without listing safe levels next to unsafe. If your going to recommend we all quit what we love to use then show side by side safe & unsafe levels. I still don’t know what a safe level is. I couldn’t find clear info on it in your site. So I have to go search it out. Info sites shouldn’t be contradictory. & You should have straight forward lists & chapters like: Pyrex…Tupperware…Mason Jars…etc…so it looks crediable not creative. Your creative site runs us around searching til we r confused & frustrated. Not informed. I have grandchildren diagnosed with CF… I don’t have time for confusion I need quick clarification. Not Opinions or Estimates. & PopScience doesn’t agree but it Also isn’t thoroughly descriptive. People need to take more time when listing things. Your taking away things that work better than modern & we love! So Facts Matter to help let go of what preserves food so well & change to modern that doesn’t work as well.
Please watch the video that shows you how to efficiently use the website – with test results for over 3,000 products it requires some additional searching for that product. The header menu and Start HERE post have most of the introductory information you are looking for. Think of it like a book – you need to read the index (or watch the video) for context about the book.

Does this go for the same looking Tupperware butter dish that is double this size? So I should toss it?
