If you get a good set, lucky you. This company has poor quality control, a lot of people on here commented the same that the lids are arriving cracked or broken. Mine also was cracked upon arrival. I have emailed customer service hoping for a replacement.

Hey, listen up! These glass containers are thick, man. The lids can be a pain to snap on some of them, but it's doable. I got them for $20 on sale, which was a steal. Even if they weren't on sale, they'd still be worth the price. The rubber seal fits perfectly in the lid and hasn't come loose, even after microwaving and dishwashing (tried on top and on the bottom shelf, of course). I can't give them a perfect score because the lids need a bit of breaking in before they're easy to latch and seal. But overall, I'd give them an A-. Thanks, Sam's, for a great product at a great price!

I've used glass storage containers for years. I typically get them at the other membership warehouse, but got these from Sam's Club a few weeks ago. As usual, they work just fine as a glass storage container, but my concern is that they actually don't dry in the dishwasher. My other glass containers and glasses dry perfectly. The only thing that never dries in a dishwasher is plastic which makes me wonder of what kind of glass are these made? I always thought glass was the same, (in this case Pyrex style glass) but these seem to be a different composition which is somewhat concerning.

The only complaint I have is that they don't nest too good. That needs to be redone. Otherwise, I love them, use them daily. Have one set, but am ordering 2 more!! Extremely easy to clean! Easy to store in the fridge or freezer! I am in the process of swapping out all of my plastic for these glass ones!

I've had few issues, but then again, I'm not very hard on them. One time only, I tried one out in the oven. I reheated lasagna at ~300°F for only as much time as I thought necessary, but after I dished some out from the side for someone else, I discovered that the inside of the remainder wasn't as warm as wanted. After microwaving a moderate amount of time at less than high power, I dug into my food. Only a few bites in, I heard a loud POP, & found that my long-anticipated treat was ruined with glass shards. The glass had shattered from lip to base in several large pieces. I hadn't set it down on a cold surface, but a cork trivet. If you're going to test the glass's hardiness, maybe don't do it in the oven & then the microwave (?)

I recently purchased this set and have been using it for a few weeks now. This may very well be the best purchase I have ever made at Sam’s! The quality and price are top notch! The glass is thick and the lids provide a very tight seal so the containers do not leak. The variety of sizes are perfect. And one of the best features is that the containers nest in each other for storage with the lids on! No need to store covers separately where they can get misplaced. I hand wash mine, but they are dishwasher safe. Upon first unboxing them, some of the seals came out, but they are easy to push back in and fit very tightly. If I could give this item 10 stars, I would! This set is worth every penny and I HIGHLY recommend it!

Don't buy them. The silicone inserts in the lids don't stay put. I have other glass containers with silicone inserts that don't come out so not sure what the issue is here. The lids are hard to get on & clasp because it seems they fit a very specific way. Again, i haven't had that problem with the other containers. It seemed like a good deal for 12 containers but it was too good to be true. I will be returning

I likes my first set so much that I decided to buy another. The new set has lids that are impossible to snap all sides on. I have arthritis in my hands but my husband can't snap them on. I thought over time they would loose up but that hasn't happened.

Storage containers are heavy duty and lids fit very nicely. I hand wash my lids and never had a problem with them fitting poorly. I however lost a lid for my 2 cup square container and the only way to get a replacement lid was to return the whole set for a new one. I'll make due for now since I feel that it's a waste to dispose of perfectly fine product for one item

I LOVE these glass storage containers. They are of super high quality. Much better than the kinds you find in the home stores. When the plastic lids lock on to the glass you can be sure it is airtight. The kids are great but a little tight at first. Once you use them a few times it gets easier. I know because this is my third purchase! I just gifted one to my daughter going off to college. I will never go back to all plastic storage. Plastic is ruining our oceans.
