Stainless Steel Mug, 16oz, Smoky Blue

Sleek, fits in your purse and drink holders. Lovely color, a bluish green, not the turquoise blue in the photo. I like the green. Lid comes apart in two pieces, very easy to clean. Looks stylish in design, compact, light. Keeps liquids warm a long time about 8 hrs. Not as long as my Thermos flask, but long enough for a day out. If you fill to the top, it stays warm longer. I half-fill it with coffee, and it still stays warm a very long time. Price could be cheaper. But it is excellent quality and I am very pleased.

These are very nice and maintain temperature very well. Hot coffee is still very hot 4 hours later. It closes securely with no leaks. The lock is nice if you're dropping it in a bag or something. Looks great and is just an all around well made item. I ended up ordering a couple more.

I will confess first, before I begin, that I have a pretty strong bias toward Japanese products. This is going back to the days when Sony had no equal in electronics, and when Toyota/Honda were leading the small car revolution. With that said, please forgive me if I sound too impressed with this home run of a mug purchase. I had heard that zojirushi made good products, but I've had some bad travel mugs and figured it could have been just another cash-in on brand power. I ordered the stainless steel 12oz because I needed a small one for easy travel (most of my travel is on foot or on bike, living in a big city and all), and when it came, I did thorough investigation of its capabilities. Immediately, I went to the kitchen sink. I filled the mug with water, sealed on the cap, locked the lid, and proceeded to turn it sideways, hold it upside-down, swing it around, shake it vigorously (while still upside-down too!), I pretty much did everything I could, short of anything that might damage the mug. Not a single drop came close to wetting my hand or anywhere else. I even wiped the counter with a rag afterward, just to see if I missed something. It was bone-dry. Next came Coffee. I love coffee, drinking several cups a day and switching to decaf so I can drink more in the afternoon and after dinner. I filled this mug up with fresh coffee, and even half an hour later I almost had to nurse drinking it to avoid burning myself; The coffee was practically just as hot as when I had poured it. I proceeded to comfortably drink hot coffee for several hours without any need to reheat or refill my mug (except of course, for more coffee). Amusingly, it even kept coffee hot longer than the insulated coffee pot did! (funny that one, maybe I should get a zojirushi coffee maker too) Lastly, the ease of operations challenge. They claim that it's easy to open this mug, drink, and then close it, all with one hand. I will admit, at first it took me a little bit of getting used to the operation, but within a few days at most I was using it fluidly with one hand, which was perfect for my commute, or when shopping at busy downtown markets. I could walk through thick crowds (this is pre-covid of course) and not have any problems with opening it, drinking more coffee, and closing it. Of course, it was still hot even when walking in the nippy winter air. This really is my idea of a perfect travel mug. You can't make it leak (even when you throw it sideways into a purse for a few hours), you really can use it one-handed, and it really does keep the drinks hot. I've done tea in this as well and it was just as good an experience; Never tried hot cocoa as zojirushi advises against milk products being used (If I recall correctly, it was something to do with the pressurized, sealed containers being able to build pressure due to milk doing what milk does). Regardless, what I've asked of it, the mug has proceeded to do with flying colors. I cannot recommend this mug strongly enough. If you ever find yourself wanting to have a small, reliable, and easy-to-use travel mug, then you cannot go wrong with zojirushi.

This is literally the best thermos I have ever owned! Temperature: I poured hot tea in it and was so busy I didnt drink it at school all day. So on my way home (10 hours later) I decided I didnt want to waste good tea and took a swig. OMG NOT A GOOD IDEA. It was still too hot for me! Even though I regretted that for a few seconds I was really surprised and impressed by this. Just for fun one time I tested it by pouring boiling water in it then 2 min later putting the cap on. I then checked the temp 18 hours later. Still hot. STILL HOT. Not warm. HOT. I do live in a warmer area so the coldest environmental temp was probably like 68-70F. With a vacuum seal that shouldnt matter but its worth mentioning. Cleaning: so easy! It comes apart and you can just wash and dry everything really well. Then reassemble in a few seconds. I even accidentally left milk and coffee go a little stinky in here once and after a regular wash there was no smell at all. That only happened one time but I was really happy about the lack of reminders of my mistake. Use: I have definitely locked this and just tossed it into my bag before. Its very secure and I have had 0 spills in 6 months of use. Also I like that when you tilt it to drink you dont get a Niagara Falls size gush of liquid onto your face. VIDEO: b/c I was confused about the parts so I thought others could use the help. UPDATE February 2015 (posted as a comment but moved here for visibility): Original video poster here! Glad some of you found my video helpful! I couldn't tell what the parts were and I thought this thermos was awesome and deserved a review so thats why I made it. Anyhow, I have had this same thermos for 1.5 years now and its still going strong. Ive taken it on lots of plane trips, shoved it in various luggages/bins to travel, really abused it as far as a thermos goes. But thats why I bought it! Still keeps my drinks unfailingly hot/cold, doesn't leak, looks great, and is still basically awesome. I even bought a couple more thermoses for family members and they are having the same success. Its worth the up front investment for this one. It does seem like a lot when you have $5-10 choices at supermarkets. I bought a bottle brush to clean it (OXO good grips bottle brush from supermarket) and it works perfectly. I don't take the whole thing apart every time- just give the parts a soapy soak/wash every few times then air dry and reassemble. 1/2023: still going strong. Use weekly or so now, I don’t think this will ever die?

Bought this to replace a similar GSI stainless steel 16 Oz bottle that had finally been dropped a few too many times. Very happy with the Zoji after over 6 months of use. I bought the smokey blue 16 oz. Like the tall/slim design, comfortable to hold, love the color. Easy to open the lid and comfortable to drink from. Keeps water and ice cold for a very long time, ice will stay frozen overnight. Easy to disassemble the top for cleaning, much easier than the old GSI.

I would give it 5 stars if a tea infuser fit, as I'm a tea drinker. This is an elegant design, efficient drinking cap that won't leak, and it holds heat very well. However, the narrow design means that none of my tea infusers fit, and I have to fold a teabag to get it in. That of course means I'll have to use a special sponge to clean it. If you aren't a tea drinker, this is a great mug. If you are...

By far the best thermo bottle and I've tried them all = Yeti, Hydroflask, Stanley, Contigo, Laken, Thermos... Zojirushi beats them all = lightweight but keep beverages hot or cold for hours, very comfortable and 100% leak proof, reliable andong lasting... Simply the best, period!

It really is the best travel mug. The lock is leak proof, the bottle keeps the heat for hours. We've had a few of them over the years and always repurchase (once one gets worn out or lost!). This is a small size, but it is perfect for having a bit of tea or coffee on the go.

El producto es muy bueno, conserva el frío por buen tiempo.

Snygg men håller inte värmen lika bra som sina föregångare. Helt ok.

Las bebidas están calientes incluso despues de 8h! Despues de 2-3h casi como lo has preparado. Es diseño muy durable. la única desventaja: un poco dificil limpiar la parte donde se bebe.
