Zojirushi Stainless Steel Mug
A stainless mug is a vacuum insulated mug that is designed to drink directly from the mug. Although similar to travel mugs, it offers better heat retention because of its tight fitting lid, and can be stored in a bag or purse without spilling.
How does it keep beverages hot?
The air between two thin layers of stainless steel that make up the body of the mug is removed to create a vacuum. Because there is no air, the temperature on the other side of the wall does not transfer over, keeping
beverages hot or cold for hours.

Keeps things hot for over half day and is a nice handy size.
Leakproof so far.
Scratches terribly easily. I am yet to wash the outside of it but even then it got scratched sitting in the bag. The outer colour coating is soft and not thick.
Don’t buy it for the looks.
I give them easily 5 stars and then some 👍
Easy to clean, looks good, easy to use. I am very happy with.

Update 2 years later: My original review stands after 2 years of frequent use. Excellent thermos, maintains temperature as day 1, paint finish as good as day 1, no chipping. Some staining internally from tea colouring, but it can be scrubbed away. It has come with me travelling, hiking and daily in the office. I have ordered another one because my partner broke the lock button on this one and finding a replacement stopper in Europe is almost impossible. We won't be disposing this one of course, it is still perfectly functional, just wouldn't trust it in my bag with the broken stopper. It's a great investment and has brought a lot of value in my life, so happy to get a second one.
"Thank you for contacting Zojirushi America.
Vacuum insulated products, such as the SM-KHE48 mug, have a 5 year warranty on the vacuum insulated heat retention of the body only. The warranty does not cover any cosmetic damage, such as peeling paint or peeling non-stick coating.
Please keep in mind:
- Vacuum mugs and their parts are not dishwasher safe nor should a cleaning brush be used, as they are not designed to withstand high heat and friction.
-Exposing the products to high heat such as the dishwasher or the use certain sponges can potentially damage the mugs and their parts.
-Do not soak the mug in water for an extended period of time.
Please be advised that this does not affect the function of your vacuum insulated mug, you can continue to use the mug with functioning vacuum insulation properties. "
By the way, my wife's mug still looks like the day she got it, even though we have always cleaned them exactly the same. I wish they would have warned me about how fragile the new paint job is...
it was awesome, at first, cleaning was a bit difficult but it was fine because it kept my tea nice and hot during the day! I would fill my flask with freshly made tea at 6.30 and would still be warm at 12 noon. i loved it! But now, the flask leaks for some unknown reason through the lid? I have no idea since i kept it in the greatest of condition? Reading through the reviews, unsure if others have been having the same problem... But otherwise the flask is amazing!
In terms of durability I have only had this for a short while and I am very careful so it has not fallen.
Cleaning is okay in that it isn't difficult but it is fiddly. This is not suitable for a dishwasher and should not be immersed in water apparently. I tend to cheat when I'm in a hurry and rinse it with hot water a few times before using again.
This fits well in my car (Ford Galaxy) as well as the drink holder on my wheelchair.
The mug keeps everything hot for hours, and the larger size pretty much gives me a flask of hot drink for a whole day. They're slimmer that the average travel mug, similar in size to a soft drink can, and so are much more "packable" than some others. The locking lid is very secure, and the only think I have to consider is to allow the drink time to cool before I head out if I'm planning to drink it on my journey. (first few times I made drinks and they were still too hot to drink 2 hours later!)
The colour of flask looks like a dark metallic navy in the photo but in reality it's more like a slightly washed out blue.
The lock mechanism is very secure and I can trust that the flask will not open accidentally in my bag.
Only downside for me is the blue finish on the flask does make it look cheap. Perhaps the black looks better.
Brilliant apart from the look though, trwally easy to take apart to clean.
