ZOJIRUSHI Zojirushi Mahobin Stainless Steel Thermal Soup Jar, Lunch Jar, Seamless 13.5 fl oz (400 ml), Beige, Integrated Lid and Seal, Easy to Clean, Only 3 Pieces Wash SW-KA40-CM

My son complained that his soup was too hot - usually he complains it is cold- has kept hot dogs, Mac and cheese, and soup hot enough for lunch. (In my own test after 4 hours water added at boiling was still 150 degrees). These work!

Kept food hot and no leakage at all.

Previously I used a small version of the older style for lunch at work. It worked well to keep the contents warm. It was not 100% leak proof and required a little care when carrying depending on contents. This was not usually a problem for me. However, I am now home and my husband tried using it and is not so careful. The lid also has more parts to disassemble and clean. Again, not much an issue for me but he was not so willing. The typical alternatives just don’t work as well or have their own distinct issues. So I was excited to see the updated version and I bought both the larger and smaller size. The lid is just two pieces that are easy to disassemble and clean. Although he he really doesn’t need to, my husband willingly did this himself. As advertised, they have been leakproof and appear to work just as well as the previous version. I can’t comment on durability given how new these are. But I am still using one of their insulated coffee containers daily after 6 years of daily use with no leaking or decline in performance. This is despite a pet that delights in knocking it off the kitchen counter almost daily and many drops while full on the garage floor as well. No parts replaced yet. My mother is also still using one of the same age. Then again their rice cookers seem to work forever. I still have my first Zojirushi that I bought in the early 1990’s. The newest is probably about a decade old now and due to a scratch (my fault) in the bowl I just bought a replacement. It’s nice to see that there are still some companies making products that last and willing to support their products with replacement parts for more than just a couple years.

See photos. Very disappointed because the measurements are not as described. The width is 9cm, not 7. Even without the cover, the inner mouth diameter is 8cm. The only correct product info listed is the height.I’ve researched on Amazon for a while and picked this one thinking it has a mouth of 7cm and will fit into the side pouch of my backpack. In reality it’s 9cm. It still fits but I can’t bring the zipper to close around it. What a bummer!Some additional info: the beige color is exactly beige. Not light creamy off white with a sheen as shown in the listing pics. So keep that in mind or you might be disappointed. Also at the exterior bottom you can see a connecting seam all around.The stainless steel quality is top notch; if you drink from it, the edge is so smooth it’s like touching nothing. The lid can be separated into two pieces for easy cleaning. There is no small pieces to assemble. This is an excellent thermo food jar and very well made. I’m taking one star off simply because the width/diameter info is wrong, almost off by a full inch.

I ordered this jar because of the warming sleeve in one of the photos. Unfortunately, it didn't come with it.Does anyone know where to get the sleeve?
