We are pleased with the quality and size of the product on our goal to reduce and eliminate our plastic food storage, cooking utensils and lunch containers . My husband has not complained about the reheating results and the cleaning is easy. I would recommend this product. No leaks, sleek appearance and sized well for a good lunch.

Nice quality, doesn’t leak, and very spacious. Great option for work.

I'm genuinely shocked that there aren't more reviews for such a well-designed and useful meal prep container – this thing is the real deal. I haven't tested the microwavability (although I've read up on the tech and it makes sense to me, it still feels like a crazy thing to try to do with stainless steel - maybe one day), but these things are virtually indestructible (unlike even the best glass or plastic containers), and yet can still go straight from the freezer to the oven up to 428 F (220 C) according to their support, which is perfect for my needs.If you're looking to get away from plastic for leftovers or meal prep, but want something that isn't prone to chipping or breaking (unlike glass), or randomly exploding (tempered glass), then stainless steel is the way to go. I bought these at the same time as a bunch of comparable stainless steel meal prep containers from Bentgo (essentially the only other company you can get "microwavable" oven-safe containers from in the US without relying on sketchy 3rd party sellers or importers) to compare, and by a landslide the Black + Blum containers came out on top.Pros:1. Build quality is pretty good - the stainless steel feels great and has good fit and finish, and the lids are sturdy and well-built2. Lids are really easy to remove (as long as you unlock the valve in the lid) - you just need to hold down on the exposed metal lip of the container below, while pulling the lid off, and it doesn't take too much force to do. I find these lids much easier to remove than most comparable airtight food containers (unlike the Rubbermaid Brilliance, for instance). They're also not too hard to put back on, other than the 1 con below.3. Containers stack pretty well when filled with food4. They come with a 2 year warranty!5. The lids are well and truly leakproof, unlike their competitionCons:1. It's a bit annoying to have to remove the silicone seal from the lid for cleaning, and you do need to remove it to be able to clean the lid. I would've preferred a design like the Rubbermaid Brilliance where the seal is attached to the lid but still easy to clean. The lid in general has a good number of nooks and crannies (thanks to the vacuum seal) that make it trickier to clean than I'm used to.2. Because the base of the container is so rounded, it can wobble around and tip over a lot when you put the lid on if you don't hold it down in the right way.3. Also because the base of the container is so rounded, the containers can jiggle and wobble when stacked on top of each other. It doesn't seem like enough to make the stack unstable, but it is enough to be weird and annoying.4. I really wish the lip was bigger (like the Bentgo Heat & Serve containers) – it would make it so much easier to take the lids off. It's still not too difficult even with the narrow lip on this container, but it could've been made so much easier.Considerations:1. I'm not sure how well the plastic lids handle heat since I haven't dared to try microwave the containers yet.2. I don't know if these are still the best oven-safe stainless steel food storage on the market in countries outside the US – from my research, you're much more spoiled for choice on this front in parts of Europe and Asia.

This is a great bowl. If you're looking for an unbreakable bowl; that is microwavable, this is it. The lid completely seals, I filled the bowl 3/4 full with water, put the lid on with the vent closed and turn the bowl upside down. Not a drop came out. The lid is fairly secure but does not latch on. I did run a test in the microwave. I placed 2 cups of water in this bowl, 2 cups in a corningware bowl which was very close in size and shape and lastly 2 cups in a Pyrex measuring cup. Microwaved each alone for 3 1/2 minutes. This bowl came out at 145°, while the other two both came out at 175°. The only caution is this bowl is just the metal, so the bowl itself gets as hot as the contents. Need a bowl for a construction worker's lunch, this is it.

Safe in microwave, easy to use and durable. Highly recommended!

This was an impulsive buy for me but I am glad I have this container. I use it as my lunch box and I love it! It is easy to clean, I’ve only hand washed it. It is easy to use from refrigerator to microwave. The size is perfect for me use as a lunch box.

Very well made. Doesn't leak and stacks nicely in your cabinet without using up lots of space. I have 5 pcs if various sizes and all have performed as advertised.
