I bought the 4-cup size, and have EXACTLY the same problem others have described. NOT LEAK PROOF. DOESN'T EVEN SHUT!!! I cannot get it threaded on OR get it shut. I think it's actually getting stuck on the little lip meant to seal it on the inside. It appears that there isn't enough gap for the top of the cup to fit. I cannot believe that any serious company would let this out their door, with their name on it. I have lost respect for Rubbermaid as a brand. I will be getting my money back from the store where I bought them, because THEY'LL stand behind YOUR junky product.

I have always been a HUGE fan of Rubbermaid products, seeking them out over any other brands on the market. Was disappointed to discover with the Take Along set of 40 items, that lids were not only flimsy--most in package did not fit containers well. For the lids that did fit, I questioned how well food would be securely sealed if put in a lunch carrier bag. Please improve this product line, I want my favorite brand--Rubbermaid--to do better for us consumers.

[This review was collected as part of a promotion.] Perfect for me to take meals to work. Seals well and comes in several sizes. I like that if I leave them at work it is fine since they are always a great price. I give these out with treat in them as well and they do not have to worry about returning anything.

What a terrible surprise when I realized, Rubbermaid no longer stands for the quality they once did. This cheap set is a prime example. Most containers are only good for one use. They crack if you look at them too hard. Don't drop one or your food will explode all over the kitchen when the container shatters into a million pieces. I was terrified my Yorkies would eat a piece before I could get the vacuum out. Don't put containers in the freezer. They will break. I'm extremely disappointed.

I was looking first for something I could make some individual meals to bring over to my mom and the divider units were perfect fit. The smaller unit's I have used for dividing portions of fruit snacks. And some I have used to put crafts in, including sewing accessories. The box they come in is perfect for many things -it's perfect size for keeping files or larger crafts. These are not thick, but you can put them in the dishwasher, and use many times. Their easy, and I love the screw on lids on some. I bought them at the reg price and thought that was a steal... I might get a 2nd set at this discount.

I love Rubbermaid food storage products but this container in particular is great. I use it all the time. It fits well in my lunch bag but is large enough to hold a good size salad for lunch. It washes easily (dishwasher safe) and I find that it does not stain even when I put tomato sauce in it. It doesn't hold onto scents like garlic and onion. It is very durable and I have been using the same container several days a week for a couple of years now and it still looks new, it's lightweight, and seals tightly keeping my lunch safe on my commute to work.

I have never been more satisfied with the price before. It was worth the wait and it was worth the amount of money that I paid for this product. Not only did I get a great product for a great price, but I also got it through the club picked up. It was quick and easy!

[This review was collected as part of a promotion.] I've used these containers for about a week now. They do there job as to storing things, however; after a few washes in the dishwasher I did notice the durability of the container itself wasn't as firm as when I first bought it.

Ummm doesn't the package say LEAK-PROOF?? I bought a few packages of these to take milk with me to work. This morning was the first time I had used them, so I put the container in a sealed bag....just in case. Good thing I did. The milk leaked all over the place. I'm very disappointed that I purchased a product that claimed to be for liquid storage, claimed to be LEAK-PROOF (which was the sole reason for buying it), and within minutes of using it, it leaked. I would not recommend these containers to anyone, especially if they plan to use them for the purpose that they say they are intended for(it says it on the package!) - liquid storage!

I've been looking forever for a space efficient single serve container line that packs well into my thermo electric cooler. I drive truck and am away from home for up to 5 days at a time and can't afford to drop 10 bucks 2 or 3 times a day for meals. These are the perfect size for both snacks and small meals and sides. They pack up nice and go from cooler to micro to dishwasher and keep coming back for more. I can cycle them for up to 10 or 15 times before discarding them for new ones which bring me to my only problem. You can't get this size in the store anymore. I've looked everywhere all over the eastern US and haven't been able to locate them during the past 4 to 6 months. Hope you guys can fix that problem. These ARE the best, and worth every penny.
