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.

A gift for my daughter. First item arrived damaged. Requested replacement and it arrived so shattered that glass shards were coming out of the bottom of the box. Requested refund this time as it didn’t appear item could be safely shipped. Still waiting to receive promised email from “management team” to handle the refund. Also still waiting on Fedex return label they said they were sending for me to return first item. Sam’s has always been the best for handling order issues. This is not the customer service I’m used to. I’m a bit frustrated at this point and very disappointed as my daughter was looking forward to receiving her gift.

I was really excited about this product so I bought a pack. They are really nice however the designs at the bottom of the containers have small areas that break really easily. The first one that broke was while it was in the sink. The second broke while stored away. The third one again broke in the sink and cut me really badly while I washed it because you can’t tell since it looks like the design. I do not recommend.

Easy to clean, perfect size.

These are much nicer than I expected. Love the silicone sleeves.

awesome just like the 6 pc set. also no noise when storing

I use every day for my food.Best organized for my food.

THESE ARE WONDERFUL, FROM FREEZER TO OVEN, NO PROBLEM

Silicone helps slipping/gripping issues. Helps some with heat too.

Bought these for my daughter so she would stop using plastic containers to take her lunch to work. Very durable and spill proof. She loves them!
