Review on Convenient & Versatile Green Direct Food Storage Containers with Lids for Microwavable Meal Prep - Pack of 10 (12 oz) by Jennifer Ford

I bought 24oz containers to use in my 6 Pack Fitness - Expedition 500 Backpack. They mostly fit - they are too big to fit in the individual compartments but you do can easily lift the bottom of the backpack. "stand" and fold them to the bottom of the bag and they fit perfectly (as shown in the photos). I can fit two of these plus the two 20 ounce containers that came with the bag. I suspect if you have a model 300 you could easily fit two of these bins and still leave room for ice packs, but there probably isn't room for a third bin. $1 each, can't complain if they break after long-term use. Since the original 6-pack containers are $5 each, although they're probably more durable, I can buy 5 of these for the same price as one of them (and they're slightly larger, which is nice). I think all containers made from the same hard plastic have the same cracking or breaking problem, but they're cheap and it's a compromise compared to more expensive/durable ones. I just started cooking as soon as I got these containers and I love eating foods that I can just reheat and eat without thinking about it or cooking anything for a week. This will help you eat better and avoid junk food at lunch or dinner. I bring my lunch to work, which also saves me money. If/when they start cracking and breaking I will definitely buy them again. ***Update*** A little over a year later I bought a second set to replenish my stash. Unfortunately, they are slightly different in design from my original 24 ounce containers, so my new containers and lids don't fit the old containers and lids, which is a bit inconvenient. Just something to look out for when purchasing.
