PrepNaturals 5 Pack 30 Oz Glass Meal Prep Containers - Dishwasher Microwave Freezer Oven Safe - Glass Storage Containers with Lids (Multi-Compartment)

I bought these because the other glass containers that I had bought kept popping from thermal shock in the microwave. I have owned these for a couple years and none have broken in the microwave. Excellent quality product. Tight seal and easy to clean. I now own 2 sets.

After reading reviews which left me with unclear / mixed answers prior to my purchasing these containers, I decided to buy them and see for myself what's up. Now that I've viewed and used them, I'll do my best to give the clear answers to clear up any confusion that other potential buyers might also have. Please see my review's photos for reference material. I marked each photo with a letter so you can 'see' what I'm talking about. - QUESTION: Some reviews say the containers leak, others say they don't. Which is the correct answer? - ANSWER: Yes and no. The compartments themselves are solid, but there is a small gap between the compartments' edges and the container lid. If you look at Photo A, you will see that I am pointing at the edges which are too low to meet the lid. Because there is a small gap, if the container is turned on its side, upside-down, or shaken around, liquids will ooze or spill between that low spot into the other compartments. That is the 'leak' people have spoken of. However, with the lid sealed in place there will not be any spilling / leaking OUTSIDE of the container; it will all be kept inside. - QUESTION: Is there a way to prevent leaks? - MY ANSWER: Yes. I used safe, food-grade silicone sealant (purchased separately and cheaply) to draw a little line of the sealant along the edges which are pointed out in Photo A. After the sealant dried, it worked as a complete barrier between the edge and the lid -- so there was no sloshing between the gap. - QUESTION: Do the compartments themselves leak into each other? - MY ANSWER: No. Aside from that small gap mentioned in Question #1 and pointed out in Photo A, there are no gaps between the compartments. Their walls are solid. In Photo B, you can see that I placed 3 different-colored liquids in each compartment, each at different levels so that you can clearly see they're blocked. There is no mixing or leaching of liquids between the compartment walls themselves. - QUESTION: Do the lids have trouble fitting on the containers? - MY ANSWER: Yes and no. First you'll need to make sure the seal is pressed all the way into its groove, just like -any- sealing lid. Then there's a specific trick for getting the lids on properly: the flaps need to be lifted outward, almost even to the rest of the lid. You can see this in Photo C. After the flaps are straight, set the lid on the container and then press the opposite flaps upward at the same time until they snap into place. If the flaps aren't even to the lid when you try to push them downward, you'll have a hard time and struggle to clasp it on; they won't go, or the lid will start sliding ajar. Once the lid is secured, however, it is on firmly and will not slip or allow leaks past. - QUESTION: Do the lids' seals fall out? - MY ANSWER: Except for issues where the seal is legitimately broken (cracked / snapped in half), the seal is supposed to be removable. You can see this in Photo D. This removal enables you to clean out the lid's groove, and to clean / sanitize the seal (else if food gets beneath and it's never washed, bacteria and / or mold will grow; this is fact for any product with a seal like this). Once the seal is dry, you can press it back into the groove with your fingertips. Make sure it's firmly and all the way in the groove, else it'll cause you some difficulty with snapping the lid on -- which, again, is true for every product with a lid like this.

Really Nice. Honestly I had bought these to split up my dog's food into portions but once I opened the box and looked them over I'll be using these for our food and give her my old ones. The pop top seal for microwaving is really handy too. I will start putting portioned lunches in them for us so we can just pop them into the microwave.

Just as advertised. Perfect size for meal prepping and fit just right in my lunch bag. Handles the microwave well, but it is a glass container so the bottom will get hot. Locking lid is nice, easy and secure; and so far has not leaked even after a quick flight to the floor after a hard break.

These are worth every penny if not more. They're 5 quality glass containers with firm vented plastic covers. I've been using them for a while and the covers haven't been damaged in the slightest, whether from the refrigerator or microwave. Only one has ever broken and that's because of the height; I've dropped them in the sink a few times and they survived without a scratch. My only problem is that over time the covers got harder to put on TT.

I purchased these containers 7 years ago and they are still going strong! I'm back to order more because they are so useful. These containers are great for freezer cooking individual portions and go from freezer to a hot oven perfectly. I prepped baked ziti, covered with foil and then the lid and froze before baking. When I was ready to cook it, I preheated the oven, removed the container from the freezer, took off the plastic lid, and placed the container on a baking tray and into the hot oven. Can't believe it took me 7 years to try this. I usually just use it from fridge to microwave. The lids are still going strong and never stained

Bought these 4 years ago and use them every week. 3 years in 1 of them got a very small chip along the edge after a big drop. All the rest are still great. Microwaving is no problem. Seal comes out so you can easily clean every part.

Bought these for the boys lunches, (7 & 8) the lids didn't make it a week. The 8 year old cracked the lid trying to open it and the 7 year old just completely ripped it off - it's no longer on the container, it's just....gone. The explanation was..."it broke off when I tried to open it". He's a small boy so I know his strength didn't do it -unless he had a Hulk moment trying to open it. It is a bit tough to open, so it's a totally understandable Hulk invoking moment. The inside does toss food around if its not secured, like you'll get those gold fish in your jelly sandwich and you'll eat it because that is your lunch kind of moments. I read about putting food grade silicone around the seams, which seems like a good idea, but you have to wait like days before that stuff cures so ... not a quick process. And I'm not that talented with trying to spread beads of silicone let alone any kind of patience with fine lining anything. Just not in my trait list. The plastic fork and knife can still be secured so its not a total loss, but I'm not sending the knife to school. It's not to sharp or anything, but...boys are...boys so...no. I do like the glass, it seems like it may survive the pavement, we'll see, if it doesn't I'll be sure to update the review. I mean, it is glass, but its a good thick glass. The portion sizes are nice in the container. I cut up a sandwich in fourths and it fits perfect in the big rectangle. Knowing goldfish are free to roam I do try to pack things on top of the movable items like a folded up paper towel so they stay in their pond. So overall a good purchase, just don't count on the top lid staying together for kids. UPDATE - 1/2020 Shattered at school for my 7 year old. Didn't get to eat his lunch due to all the glass. So...looking for something else now.
