No matter how hard I try, I can't get all four snaps to lock.

Very good deal! I love the silicone covers. And snap on tops. Keeps it safe from chipping. Very pleased with my purchase

Wonderful glass containers. Great variety of sizes and very well made. I definitely recommend these.

Love the color coded lids! We always had trouble matching our lids to the dishes & this makes it quick & easy.

Love them!

These are great! I've owned them for a couple years, no issues. I'm not sure what those 1 star reviews are doing with theirs, but they're not fragile. I can only assume they aren't using them properly or have received a defective item. The person who had one break in the oven it sounds like they put cold food in a hot oven which will crack the glass. I never understood people giving 1 star for an item arriving broken. However Sam's will replace if they arrive broken. I've used these in my Breville oven, the microwave and I put them in the dishwasher. I do take the rubber cover off for oven an dishwasher. Highly recommend and have given as gifts everyone loved them and actually bought more.

I gave it a 4 because one of the lids did not fit! Otherwise they are just what I was looking for to fit in my Hot Logic food warmer!

Love the silicone, my kids use these and the silicone prevent a lot of dropping/slipping. Noticeable difference in keep food fresh. East close tops

Dura-Glass containers are really nice just need to be a little bit bigger. Love the silicon jackets that wrap around the glass, easy to warm leftovers in microwave and helps prevent burn when removing from microwave. Clean up is easy.

I got these to you daily, trying to get away from plastics. I love the silicone on the outside feels like if I did drop my lunchbox they would not break. Great suction from lids sometimes makes it hard to take off, but that means no leaks.
