Love these. They are thick glass easy to clean the seal is on lid it does not come off. The lid creates a good seal and they just look nice. And are stackable. I already bought a second set and debating on buying more. Just becasue I use the bigger containers more ( i wish they sold the larger sizes separately). I think the price is worth it to even just use the one. Everyone needs a good tupperware ware set and this is the one! I will be buying more for gifts.

I looked at Consumer Reports to see what they recommended for glass storage containers. Those made by Glasslock topped their list. When I saw a Member’s Mark set made by them at a great price I snapped up 2 sets to replace all my plastic pieces that I had. Glass is better for your health when using it to reheat in the microwave, and these are also oven safe (not the lid obviously). The lids give a firm snap, with a few of them being a little harder to snap than others but they all have worked great at containing what’s inside, even liquids.

I bought these to replace a huge mess of mismatched containers that I collected for years. These things are great you can reheat anything in them without melting or discoloring them. they clean up great and the best part is they stack so nicely they take up less space that just the lids for the containers I used to use.

Solid set. Have no issues with lids not fitting. Really like that all the “squares”can be nested in one set and the “rectangles” in another for space purposes. Fridge to microwave to oven to freezer is also great. (Be mindful of lids accordingly.) Not using my prior storage containers since buying these!

Well, just a little disappointed about the delivery of my containers, after I started to wash my containers I discovered that three of my tops was cracked, but otherwise they was fine. Didn’t return because to default to repack them. Tried to add pictures no luck.

I have used 4 containers since this recent purchase. The lid on one of the square containers has cracked and broke already at the first use. How do you return just one defective part? I am still trying this product. When they arrived, many of the seals pulled out from the groove that they belonged into.

I know I'm old, almost 77, but these lids do not close easily. I have a very hard time sealing them and most of the time I can only get three of the flaps to hook. This happens on all sizes. I really feel this was a waste of my money. I wanted to get away from the plastic containers and use glass but I feel I will have to look for a different brand some other place. When I read about them I really felt these would do the trick but now I fully regret my purchase. If you have grip strength maybe you can get them closed but I find it impossible to do. I'm glad I have plastic wrap to seal them with.

Bought these to replace similar plastic storage. The glass containers are awesome and space saving with the complete nesting feature. However the lids are awful! Several were broke when I opened the box and several other tabs have broken after being used a few times. The crease that goes over the lid to secure the flap has cracked and basically makes the lid unuseable on the broken side. SAMS was awesome in refunding my money; no questions asked!

Really like the product but the lids do not last very long about every six to nine months they brake and have no lids anymore. I have looked on line and found that just to buy the lids cost more then buying a new set but I don't have the room for all that glassware with no lids.

I bought these last month and just opened to use. The lids are breaking already, or were already broken. The flaps that "lock" onto the containers are snapping off...super cheap! I was really excited to get these, because they're square and rectangular shaped (I already have round Pyrex storage dishes.) I guess MM quality just isn't there. :(
