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.

These are excellent, do everything they're supposed to. Were pretty low cost too, glad to have purchased them. May purchase more in the future. They were so easy to use and put my lunch in, to take to work, the design of the seal made taking it on the bus easy. I has a nice look and is very functional.

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.

Overall pretty good, but the plastic cover for the utensils broke off on one of them. The glass container itself is good and sturdy.

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

Switching from plastic to glass is so worth it! No more staining, no more scratching, no more replacing worn plastic containers every year! These are now our go-to containers for leftovers. We usually make enough of our dinner meal to have leftovers for lunch the next day, so the hot meal goes right onto our plates for dinner and into containers for lunch. With our old plastic containers, I'd have to wait to seal the lid, otherwise it would create a vacuum in the fridge as the food cooled. If you've ever had this happen, you know how difficult it is to get that lid off! With these, I can put the lid on immediately and just open the vent. It's such a small feature, but I love it! For reheating food, these are great in the microwave where you can keep the lid on and open the vent to prevent splatters, but they can also go in a toaster oven or a regular oven without the lids. Foods like pizza and breaded chicken taste so much better when reheated in the oven, so this is a big plus over plastic containers. These are also very easy to clean. I put the glass anywhere in the dishwasher, but I usually hand wash the lids. The sealing ring in the lids can also be removed if you need to clean it. My first set of glass containers like this was the Vremi 18 Piece Set ( Vremi 18 Piece Glass Food Storage Containers with Locking Lids - BPA Free Airtight Oven Freezer Dishwasher and Microwave Safe Food Container Set - Small and Large Reusable Square Food Containers ) which I love! However, I wanted a few more of the larger size so that we could put that day's in the dishwasher and still have containers ready for the next day. What I received is actually a little larger than the description...30 oz and 7.4" x 5.6" x 2.5", but they complement my Vremi set perfectly! The 30 oz Prep Naturals containers are right in-between the two largest Vremi sizes (27 oz. and 35 oz.), so the three nest together. The Prep Naturals containers do not nest with themselves, but I'm very happy that they will nest with my Vremi set. These are the perfect size for leftovers, but they also easily fit a sandwich made on regular-sized slices of bread (if you're more into subs, two of the 6-inch Arnold steak rolls will fit!). Like my Vremi ones, these snap tightly closed, and I haven't had any issues getting all four snaps to lock down. If you do have trouble, try closing opposite sides first. If you close adjacent sides first, it makes it harder to get the other two sides to latch down because of the angle created by the two that are latched. I've also found that applying downward force as you push in makes it easier to latch. I hope that helps!

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.
