Rubbermaid 7 cups Food Storage Container 3 Pack Clear

while heating in microwave oven the container wall is burned.

Always a favorite - and you don't have to go to a Tupperware party to get it. My wife always microwaves food in them - I'm not totally comfortable with "Microwave Safe" labeling, but I do like to store stuff in them (no bugs, work well in the fridge).

I've been using these red top containers now for about a decade, and I still have most of my first purchase. A few have been given away, stolen or lost. I've bought some extra so that I have new looking containers to take to potlucks or as a guest. But I'm quite sure that I haven't actually destroyed any of them. They are in daily use around my house and on average I have about 6-8 of them in the fridge at any one time. All the lids still fit securely and there are no abraded edges. The biggest culprit for damage to these [as far as making them not look good, though still functional] are tomato based foods like pasta sauce or chili. It can add a bit of stain that doesn't come out for a couple of washings and/or erode a bit over time. However, over the past year or so, I've started spraying the inside with cooking spray, and it certainly helps with the staining. Otherwise, these containers get a bit of etching on the clear plastic and look whiteish and not new, though they remain functional. Still, with the cost of them, I have no intention of switching to something else. Not even Tupperware has outlasted these things, and these are a lot cheaper. I needed some larger containers with doing more cooking this year because of COVID, so I got a few of these and some for my adult kids. They are great for soups and I don't think I've ever had one leak with reasonable food handling. The one exception would be if I've stored some hot food and the pressure burped a corner loose. But this works for anything and better than any storage container short of a screw top or a mason jar storage container. I just put it on the table, lay the lid on top till it heats up the air and burp it a couple of times. I've also had a corner pop loose in the microwave if I've not popped it loose in advance. Both of these situations have been remedied by the addition of this burp valve on top of the red lid. Now I can just crack that loose and put it in the fridge or the microwave without concern. Kudos to the Rubbermaid folks for this rather innovative yet uncomplicated design change. I don't know if they are doing this on all of the tops or just a few. It's not often needed so I'd hate to see an expense that isn't necessary, but I know I'll happily take this on a few of them. Technically speaking you aren't supposed to use these for cooking. However, the instructions say that 30 seconds in the microwave won't be a problem. I've found that to be true except for fats. Fats will get too hot for these. As for sizes, I like the variety though I'd happily trade 20 of those tiny containers for one 7 or 9 cup. The tiny ones are great for storing a bit of salad dressing or diced onion, or taking a minimal amount of sauce on a picnic, but that's about it. I suspect the only reason they are there in that number are to boost the number of containers on the packaging. 5 stars easy, but pay attention to sizes and be willing to pay a bit more for getting the sizes you need.

Me gustan mucho estos contenedores, he comprado varios, son excelentes

These were bought as a gift and the reciever was actually excited. 😂 They use them as easy to carry Cereal bowls. It works and they are easy for them to carry one handed with the rim. Easily washed in the dishwasher and can be used in the microwave with the vented lid. Most likely will buy again if they end up staining them with continued use. Rubbermaid never let's you down with quality products. 5 ⭐️'s from me and the reciever of this gift.
