I didn't download the materials via this purchase - I got them somewhere else - but this diet is fantastic. After trying a million things, and finally deciding that I absolutely had to find a non-gimmicky diet that just really taught me the right portions for everything, this was recommended. It has been fantastic! In about 3-4 months I've lost 30 lbs and I'm forging ahead. I've adopted this as my new way of eating every day (rather than just doing 21 days or whatever it says), and within the first month it had done away with my sugar cravings (and carb cravings in general) and my 'cheese' cravings. As for the containers themselves: they were useful for the first couple of weeks - I'm so used to the portions now that I don't really need them, but I do still pull them out from time to time when I'm unsure, and I do use the orange ones frequently, since I travel a lot - so I pack my seeds in them and take them with me. They've certainly held up well, and they all close properly all the time. I only lost one to the dishwasher in a great orange melt - but it's not the container's fault. It was one of the orange ones, they are so tiny that it's hard to keep them secured on the top rack - it fell and melted at the bottom of the dishwasher. I now put them in the utensils rack, and even though that's on the bottom rack, they've held up excellently, and these little orange ones are the ones I actually still use very frequently!
