I have purchased 3 sets. This glass set is amazing and space saving. Nest inside each other. Heats perfectly in microwave amazing. Lids are leak proof. For the price I can not get over the quality of the set. And the nesting from the small to large and lids fit while nesting is a winner. Go buy these glass sets.

Like everyone else is saying, I should have checked the reviews. The lids do not fit. After I wash them I was putting them away. I found two little chips of glass. They are very breakable. I do not recommend these at all. We're taking them back to the store.

I just left the ER because I had my lunch in one of these "shatterproof, tempered glass" containers and I did not see these very thin shards of glass from the inside of the container. The shards of glass looked as though someone "peeled" glass from the inside of the container. I was eating chicken & rice/gravy and ended up with a piece of glass in my mouth. Thankfully I did not ingest that particular piece, but the ER said that they were so small that the tests would not show up. SO PLEASE DO NOT BUY THESE AND TAKE A CHANCE OF GLASS IN YOUR FOOD. The lids go on much too tight and we think that because of that, it puts too much pressure on the sides of the container. The inside of the dish had the broken glass from around the inside edge. PLEASE BE CAREFUL. WE DON'T WANT ANYONE TO EXPERIENCE THIS. This was extremely frightening and I still do not know if any glass was ingested. My ER bill will be over $700, so we are out that money too. However, so far so good and I will consider myself blessed that it wasn't worse. See attached photo. You can see that the glass is thinly shattered around the inside area up near the edge. They were never dropped or mishandled. The issue is strictly around the edge where the top goes on. Needless to say this was extremely frightening. DO NOT BUY THESE!

Very well made

I just purchased this and all but the two smallest ones were warped and didn’t sit flat. The quality control is horrifically bad. With so many pieces bad, I am not going to waste my time trying again - so it’s going to be a return instead of an exchange. This product has been on the market for a long time, any problems should be ironed out. I really didn’t need my time wasted like this.

I just bought these 2 weeks ago. Upon taking the containers out of the box, the smallest lid was stuck so hard to the glass container that the seal tore apart. Today as I was cleaning a lid, another seal ripped when I removed it. The lid does not work without the seal. Then I removed a container from the freezer and the lid is broken on the corner. I made sure to allow room at the top for the food to expand as it freezes and the food did not even reach the lid. I have been successful using these a room temperature but really wanted to use them for frozen storage. The Glasslock website has replacement lids mentioned but may not be available until September. I feel I should not have to buy new lids already. I guess I will keep the set and use for everyday leftovers.

Purchased these to replace our assortment of plastic and some glass storage containers. Love the square and rectangle design as they take up less space in the frig. The lids do snap on kind of hard but I am assured they will not leak or let air in. Like the fact that the containers are safe in all usages and realize the lids are top shelf dishwasher only. When we return to our non winter home we will be updating our cabinet with these and no more searching for the various lids for the containers we have.

I was very happy with the weight of these containers and how securely the lids fit. They make great storage containers but when reheating green beans in the microwave, the dish shattered. I did not have the lid on it (since I understood they were not microwavable) but when the beans heated up, the entire bottom of the dish cracked and shattered.

I bought these thinking I'd like to stop using plastic so much. These have been a great choice for me as I can use them for hot foods, for lunches to take to work, and for basically everything -- without worrying about a plastic taste or storing too long in plastic. Lids seal very well and all parts are dishwasher save (lids in the top rack).

[This review was collected as part of a promotion.] I really like this food storage set. It was glass and the lids really sealed well. I also liked that they could nest for easy storage. There was a good variety of size that could store many different components of a meal. They are durable and heavy duty and seem like they will stand up to microwave well. I would not microwave the lid .the one negative I had is that when nested sometimes they got stuck a bit and had to jiggle to free them.
