Was excited to receive this set. The first time we used, the glass busted in the microwave within 30 seconds. I have contacted Glasslock, and hoping that they will send a replacement. Also hoping that this does not happen to any of the other containers we have not used yet! OMG! In less than an hour after emailing Glasslock, a customer representative called me apologizing for the cracked container. He is sending a replacement right away. What awesome customer service!!! Hopefully this was just a rare occurrence.

[This review was collected as part of a promotion.] I only use glass containers (as opposed to plastic) and I was so happy to get this set by Glasslok. There are plenty of containers of various sizes which is perfect for everyday use. I use the smaller ones for baby food and leftover sauces. The bigger ones go in the oven, for reheating or baking. Overall, love this set and definitely recommend.

I was just washing one of the containers out at my sink and it totally exploded and cut my finger. The water was like lukewarm. It wasn’t even at its hottest and the bowl had sat in the sink until I was ready to clean it so it’s not like a big difference in temperatures. It had been in the refrigerator, not the freezer. I haven’t used any of these in the freezer so far.

I bought this product but one of the lids cracked along the edge so it wouldn't seal properly. I sent an email twice to their customer service email (glasslocks@outlook.com) and requested a new lid. Never heard anything back from them. Does anyone know how to contact this company?

I bought several of these for gifts and myself. I had a odd defect in the first box I opened, one of the locking tabs was missing. Sam's Club was quick to exchange the entire box without any problems. They have a nice tight seal, and the gaskets are made to come out for cleaning. Highly recommend them. great for leftovers and for taking lunches to work.

After a couple of months of irregular usage 2 lids of 4.1 cups rectangular containers broke which makes them completely useless. As mentioned in another feedbacks, lids are very hard to open-close. I noticed that plastic became very tough while container was sitting in refrigerator which made the area where leaves bend on the lid to become very fragile and to crack.

Bought this item and used it or the first time to take lunch to work. Product says microwave safe, tempered glass and shatterproof so I assumed it was safe. Lunchtime came, I put the container in the micro to heat up my lunch and the darn thing shattered! See pics. Ruined my lunch and had to eat a bag of chex mix:( Waste of some good Mexican food!

The glass container is of good quality - but the lids are of cheap, flimsy plastic. One lid was cracked (at crease where the lid snaps onto the side of container - see photo.) When I called Sam's Club to get replacement lid, I was told I'd have to take lid to club and request replacement. I'm too busy for that. I have similar containers with snap on lids that are far more sturdy. Sad to see such inferior quality with Members Mark - wont be buying that brand again. My photo shows competitors brand lid (top) vs Members Mark lid.

One lid is missing the snap

Perfect sizes for all needs and great price!!!
