Here's a good hack tested by using an almost identical Nissan product: Put drinking water in the top container, freeze it, and then put it on top of the stack to keep your cold food cold the whole day! And you can have a cold drink to boot when the ice melts! (Of course, you're trading off more food for more cold, but the method has not left me wanting -- three containers of food is working out well. ) Qualification: This method places the Nissan in a soft-sided insulated lunch bag, which helps keep it cold, but am confident the contents will keep cold the whole day without the aid of an insulated outer container / bag -- typically, will have a substantive piece of ice left over in the top container at the end of the day if eating late. You'll experience condensation on the top of the bento container -- good idea to put the bento in some sort of bag for extra insulation. . . . Pulled the Nissan out of storage when considering this drop and started using it again for cold lunches, and came up with the hack a few days in, when thinking how to maximize cold retention. It's helped to minimize weight, as typically would have multiple oversized containers within the insulated lunch bag along with one of those ice bricks you put in the freezer. Am planning to make lunches ahead of time in multiple bento containers to speed up the morning routine. Hope this helps and enjoy your new Zojirushi :-)

I'm honestly surprised to see this on Massdrop, and I think it's good to give a bit of a review on these. I purchased 2 sets of these over the years, and have had mine for about 10 or so years now.
The build quality is quite good. There's a main holder of sorts, that holds 4 containers. The idea behind the thermos is that it's more insulated at the bottom than the top, with an insulation layer between the bottom and the top. This is largely with the "large container" (2nd from bottom) where it has a fairly thick piece of styrofoam in the lid. Meaning, that if you have warm/hot food, it should stay warm by the time lunch rolls around, but the top two cups won't be as warm (and the very top is largely unheated). Each container seals quite well, and there's not much, if any leaking. Also since there's an outer shell - even if an individual cup does leak, the likelihood of it getting out of the outer container is minimal.
This setup can hold warm, or cold foods. Personally, I'd recommend only doing warm in this though. A common meal for myself (I work from home a lot now, so maybe not as often) is the following: Lowest Cup - Warm Miso 2nd Lowest Cup - Rice, plain 2nd Highest Cup - Veggies/protein (goes on rice) Highest Cup - Fruit and/or some kinda desert or nuts.
When I was using this every day, I'd prepare my meals in the morning. A rice cooker, set to start before I got up had the rice done by the time I got up. Frozen veggies, left overs, etc would be added to the 3rd highest cup. Miso is very quick to make, I have a hot water warmer I also have ready before I wake up. That, plus some miso, and a bit of microwave = decent miso. So 3 of the cups can be prepared fairly quick. Desert is usually prepared the night before. All of it stored in this, thrown in my backpack with either chopsticks or a fork in the side, and off to work.
It's also worth noting that this is much larger than one may expect. The dimensions should be available, and I'd get out a ruler and measure everything. Reasoning being is that this may or may not fit in your commute bag. There are many other bento-box like setups, some that are cheaper and smaller. The main area this one succeeds at is that it can keep your food quite warm/hot til lunch. If you're aiming for food that's more cold that you can microwave at work, then I'd look toward other solutions. It's not so much that this can't do it, but there are other solutions that include ice packs that you can add to an insulated bag to keep things cold. I have one of these, too, but I don't use it nearly as much as the Zojirushi. Also note that this thing holds a lot of food. Easily enough to have a snack or two in combination with a meal for lunch.
Personally, I really think the Zojirushi is fantastic for my use purposes. I bought mine awhile back, but it doesn't appear the design changed much. If you're into bentos, especially warm Bentos and don't mind carrying a bit extra, this could definitely fit your needs.

Good to hear! Will the contents of the inner bowls spill out within?

I think it'll depend on what you're putting where.
The lowest cup is a screw on, and is pretty much resistant toward leaking. The one up from that isn't sealed quite the same way, but still has good sealing. The other two are snap lids, and while are snug, I wouldn't trust stuff like soup in them.
That said, if you're storing stuff other than soups, including heavily seasoned/liquidly things, it should hold. For example, in the top compartment, I can have fruit like strawberries and some liquid and they never leaked so far. I think as long as you have the container upright and aren't crashing in a bus/plane or doing twirls off a high dive with it, that things shouldn't leak.
The lowest compartment/cup is kinda designed specifically for soups though.
With shipping and handling, the current price of the non silver ones, you save about 20cents compared to Amazon. Amazon has the better deal for the silver ones at $35ish. So if you have amazon 2day shipping, might as well buy there.
Would this keep the smell of the food inside?

Honestly I haven't had too much of an issue with mine. I think it largely will depend on what you're storing. If you're doing a lot of fermented foods, I can see it keeping that smell in more. But, I use mine for miso/rice/veggies/desert, and have used mine for years with no real leftover smell.

"Food"
I've had one of these from a while ago. They dont do dish washers very well, but the concept is pretty clever. I'd suggest it more for bringing food into hospital patients, or when caping, rather than a daily lunchbox. This is purely cos it holds way too much food for a daily carry

Caping? Sounds fun. Is that were you don a cape and then find a stoop to hang on while eating your meal from the Jar? I am down if it is. :P
It seems heavy at 33.2 oz empty.

If that's the case, they should market it to construction workers. :D
How is this a "deal" when it is available at Target and Amazon (the sliver one) for $1 more.
I wonder how long this would keep ice cream as ice cream? The statistics they give aren't relevant.
I'd love to be the guy with ice cream to share on top of the mountain

So true!
And then you have an ultrashit after your ultrahike. :P
$35.30 with free 2 day shipping on Amazon..

The Silvered color option is $35.30. All others are between $43 & $44.
Is only one of the compartments water tight? I feel like this is just begging for leakage.

Only the bottom most container has an o-ring to protect spillage. The next one up has a twist seal and the top two have a lid that fits over the edge. Unless you're tipping the container upside down all the time, you might have problems.
I like that it fits vertically in a backpack. Most of the time, other lunch containers are different shapes and don't fit the bag perfectly so your food gets tossed around even more.
Are these jars 110v or 220v? How fast can they cook a 24lb turkey?
RayF
They are solar powered only and more specifically can only convert rays from the Land of the Rising Sun. :D
Can you use the main container itself as a large thermos?
Mrbill
No. The top of the main body is not insulated and is not watertight.
These are great for GREEN......very cool and keeps it FRESH!!!!
The heat and cold retention numbers are missing the starting temp. They are kind of meaningless without that.

Massdrop seems to do this with every Zojirushi drop, even though it has been pointed out before on other drops (kind of like how the Seiko SKX013 photo they use is the wrong watch, but it keeps showing up again and again with every re-drop... seems like a simple fix). It appears they simply copy and paste the info from the Zojirushi website without understanding you also need the following details: HEAT RETENTION: *Rating is based on water at a starting temperature of 203°F (95°C) at a room temperature of 68°F (20°C) COLD RETENTION: **Rating is based on water at a starting temperature of 40°F (4°C) at a room temperature of 68°F (20°C)

I noticed the description was almost the same exact thing on Amazon. I suspect it’s probably whatever copy they supplied to retailers.
Thanks for finding the numbers.
I love my Mr. Bento.
