Stainless Steel Mug, 20 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.

The best coffee transporter ever! Keeps my coffee hotter and longer than my work day. Given many as gifts; all were hits. It’s also easy to clean.

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.

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.

I have so many coffee containers, and this one is the best I've found,stays hot very long and is nice color.

I don’t write a lot of reviews but once in a while a product performs so well I almost feel obligated to add my 2 cents. This travel mug is hands-down the best I’ve had over a lifetime (I’m 38) of coffee consumption by a landslide. Just to be clear, I’m reviewing the 20 oz. Zojirushi slick steel travel mug in black. I made sure to get the slick steel because I avoid Teflon like the plague. They do offer a Teflon-lined version if that’s your thing. I spent more time than I’d like to admit researching a travel mug prior to purchase in part because I’m always so disappointed in them. I pulled the trigger on this one because it checked all of MY boxes: minimum 20 oz., leak-proof, locking lid, and EASY TO CLEAN. It meets all of these criteria in spades. The lid comes apart into 4 pieces and each are sturdy and easy to clean. It’s also very easy to disassemble and reassemble. I believe you can even purchase the rubber gasket separately if it degrades over time. It’s obvious that someone put some thought behind the design of this thermos. It is so efficient in retaining heat that I’m still amazed regularly almost a year after purchase. My biggest complaint is it’s almost TOO efficient in that I leave the lid open during my commute so it cools to a chuggable temperature more quickly. If you’re diligent about closing the lid after sipping it will be warm 10 hours later. It’s really remarkable. I’ve dropped it HARD a lot and it’s completely fine except for a small dent after dropping onto concrete which is my fault. It’s so narrow it fits in ANY cup holder or side pocket on a backpack. That is important to me because It’s hard to come across one small enough in circumference to achieve this and driving with hot coffee between your thighs defeats the purpose for me. It does NOT leak. At all. And the lid locks and stays locked. I can put this in a backpack upside down if I wanted to and it wouldn’t leak. It’s hard for me to choose anything I would change. The black paint is a little bit sparkly which I don’t love and I suspect the chink in the armor is the hinge on the lid but I haven’t had an issue. I’m just guessing that’s what will go first. I Love it. Buy it and don’t look back. I have heard there are some counterfeits out there so just be aware of who/where you buy it from.

The best tumbler to keep your coffee hot for longer. I have tried several tumblers, and this is (by far) the only one that kept my coffee hot (for more than 6 hours - believe it or not)
