Freshware Meal Prep Containers - 21 Pack

I am trying to lose some weight and I use these containers to prep my meals for the week and help me adhere to my diet plan. I find them these containers very convenient and appropriate for my diet plan. The main compartment (12oz) is large enough for my protein (which is the largest portion of my meals), while the 2 smaller compartments (6oz ea) are adequate for my vegetables and/or side dishes. They work well in the microwave to reheat meals. I have frozen meals in these containers and reheated the frozen meals in the microwave with good results. They are a bit hard to clean and a few of them have chipped around the edges in the dishwasher, so I would not say they are heavy-duty. I do wish they were slightly more "heavy-duty". But, I have found that with proper care I can reuse them a half-dozen times before they need to be discarded. After a good wash, they don't stain or carry-over food smells from previous meals. At the time of my purchase I found the price to be reasonable for the amount of times they can be reused (~$.65 each), however I noticed the price has gone up significantly since my last order (now ~$1 each), so they are getting more expensive and that concerns me. Overall very pleased with this product, but, will be looking for other suppliers as the price continues to go up.
