Zojirushi Stainless Steel Mug, 16 ounce, Black Matte

I was disappointed that this does not come in many colors. Well, that is if you do not want the coated (inside) version, and you want the bigger 20 oz size, I think this is the only Zoji option. And I definitely did not want orange (or Pac Man?!?!), so I got the black one. It is actually very nice, so I no longer mind having to get black. It is not a boring gloomy solid black but kind of metallic (like paint on a car, but not glossy). I had gotten a different model for a smaller 16 oz size -- the model with the fatter cap and straight body. I like that one too. Both have what are called "SlickSteel" interior but this black-or-orange model is not as shiny inside, so apparently the Zoji process for making it has changed. Also, this one has one less gasket (one instead of two rings) although I did not mind two. I like that the rings can be removed for cleaning and also that you can buy replacements. In fact you can buy replacement lids in case you break the lid. So I think these will last me a lifetime. Both models hold the temperature extremely well, and both look great. Also, most people probably already know, but the State of California warning on the packaging is just because the product is stainless steel, and stainless steel is made with chromium and nickel (which is "known it the state of CA to be toxic...). The chromium does not leach out and harm you. Really the only reason the label is on so much stuff is trolls bring lawsuits against companies to collect money because of a crazy law, and the label protects agains those lawsuits. It is too bad because it alarms some people. Do some research and don't get upset about the scary labels.

This is now my new go to tumbler. I started drinking hot tea because of my sinuses. I found my old one would not keep my tea hot overnight. It would only be lukewarm. This one, hot as can be the next morning. I have even grown to like the color. I preferred the black one but, for ten dollars less, I chose the orange color. 🙂 The top mechanism works very well for opening and closing. And it's the perfect size for a 20 oz tumbler. All around, it's a great tumbler that does what it is supposed to do. And does it very well.

Yes, this travel mug does a good job in keeping hot beverages hot, and cold beverages cold. I bought this (& a different Zojirushi model) to replace a pair of older Zojirushi travel mugs that got badly damaged. Those ones lasted a good couple of years, even after getting dropped multiple times. It was until after they flew out of a moving utv and were accidentally run over that it was time to eulogize their usefulness, and I had desperately sought replacements. This was the closest I could find to the last model, and this one is the most comparable in terms of function & style. Pros: flip-top allows easy access to drinking straight out of your travel mug using one hand, size is about right (not too little, not too large) & keeps a relatively slim profile. Cons: not many, but those that have a hard time with keeping track of parts & pieces, it could be easy to disassemble and misplace all the fittings that go into the flip top lid (total of 4 including a a couple of small silicone gaskets that can easily disappear on your dish rack & before you know it, you've got a leaked spill all over you). Good value on the mug. It's not cheap, but worth the investment considering how well sturdy these products are. The outside of this one has already accumulated some scratches, but those are minor cosmetic scuffs that don't affect the overall durability on how well insulated the travel mug is itself.

I don't always like to drink from a 40 oz sippie cup like a toddler. Sometimes, like at work meetings, I prefer something that's portable, sleek and adult. So easy to slip into a bag, and never leaks a drop. The heat and cold retention is great, and so. easy. to. clean. Love this pretty orange color too.

The good: Keeps water cold (with ice) for 24+ hours. It has kept hot liquids hot for similar times, though I mostly use it for water. The size and shape are great. The mug lid is so easy to open to take a sip, and stays closed and leakproof even without the lock activated. With the lock switch, you could basically throw it like a football across the room and nothing would come out. I feel comfortable tossing it inside my backpack with liquid inside and know it won't leak. Not so good: It's 2 years old now and looks great on the outside, but the inside rubber parts and plastic parts are very difficult to clean. The rubber stopper thing has dark brown sludge that won't come off. I got a little bit of it off via Barkeeper's Friend, but it won't all come off so it must be embedded in the rubber. I just ordered a replacement rubber part via Zojirushi so I hope it fits, but that's $9 down the drain for a piece of rubber. Even the hard plastic area where you sip out of has a narrower edge that is very difficult to clean. I'd need to pull out a very narrow brush to clean thoroughly. Of course, none of this is dishwasher safe. Moving on: So, for my daily coffee, I'm buying another brand that can go in the dishwasher and doesn't have those rubber/narrow bits. I won't be able to toss it in a backpack but that's OK.

As a guy, I'd prefer these thermo mugs to be somewhat thicker; girls would probably like them slim. Generally speaking, of course! That say, the form factor does not take my enjoyment away from them. They keep warm water warm and cold water cold, for hours! They are leak-proof and have a lock for the cap to avoid unintended spills. These flasks are really well-built, a testament that Chinese manufacturing has come a long way, as long as the brands are willing to pay for their higher-end production! I bought 2 of these Zojirushi thermos and they have served me well since! I'd not hesitate to recommend them to anyone, even beer-mug-loving guys!

This thing is amazing in winter - but I already knew that because it replaced the 12oz version I lost on a bus. Liquid you put in, basically stays at the same temperature overnight. Put coffee in at 180F at night, it may be 160F in the morning (especially if you pre-heat the inside of the thermos, as physics still applies). If you want to drink coffee you make in the morning with lunch, better add a bit of cold water. In summer, I've been starting to use it to keep cold ice-tea or water on my desk. Usually it gets refilled every other hour, so not much of a challenge. However, unlike a glass, it does not sweat on the outside, so it prevents soaking stuff on my desk. But last Saturday, I put it empty in the freezer to get cold, filled it with ice-cubes and added ice-cold water from the fridge. Then I drove to a park and left it in my trunk. It was 95 outside. I went for an overnight backpacking trip, and came back the next afternoon, more than 24 hours later, 96F outside. The car had been sitting under a tree, so there was some partial shade. The Thermos still had a lot of ice in it. I drank the water (best thing EVER), and threw the thermos with the remaining ice into my pack. When I unpacked in the evening, it still had ice in it! Obviously, melting ice can absorb a lot of thermal energy, but this is the first time I used that thermos to keep stuff cold that long. I find the top easy to completely disassemble, clean with a brush and soak overnight in soapy water to keep it hygienic. I only do this roughly every other week - it really gets used too much for gross stuff to grow quickly. Otherwise I just fill half way with warm soapy water, close, shake, pour through spout, repeat a few times with clean water. Soak 1 hour in a mild bleach solution only after I abuse it as a cocktail shaker for a drink involving raw egg white (hey, when bars are closed, a woman has to do what a woman has to do). I've never had any problems with leaks. It gets banged around a fair bit (like falling of a table or being at the bottom of a bag that gets put down roughly), and so far shows little wear. Great one-hand operation to open, drink and close while driving. Only things I would improve: - make the lid open at a slight angle to the drinking spout (as opposed to right opposite of it), so that those of us with a European equine nose don't end up with a brown coffee spot at the tip from touching the part of the lid that seals the drinking hole. - add a way to attach a lanyard. - maybe allow for a slightly higher flow-rate. Do to the design, if you pour just a little to fast from this thermos, it splashes quite a lot

Incredibly durable. I've cared the same Zojirushi 20 oz for nearly 12 years. Finally gave in a replaced the dinged and scratched favorite merely to clean up my act. It truly keeps my coffee cold from the moment I fill it. Sometimes, when I am returning home in the evening I can still have the last very warm sips to finish. Never leaks and is truly one handed for on the go. Fits easily in cup container slots in cars and makes a mean night stick style deterrent to anyone trying to get frisky late at night. All in a great Coffee thermos. Does ice cold beverages as well. Though I'd recommend getting a second one for just cold. Costs a bit more but truly worth it. 5 stars!
