Zojirushi Stainless Steel Mug, Black, 16 Ounce

I love these zojirushi insulated bottles, but wasn't sure if these ones on Amazon were the real thing or not. I've always ordered directly from the website in the past and they do have free shipping, which is nice. But the price on this was so much better that I decided to try it. It came in the exact same packaging as the ones directly from the maker, and seems to be of the same high quality. It is a nice size, keeps my drink cold or hot and I've dropped it so many times, but no hard besides a few scratches. One thing is if you're going to use it for coffee, that's all you can use it for. I use it for water mostly, but my husband put coffee in mine and I could get the smell out of the one small rubber ring. Everything else cleaned up odor free. You can order the parts if you want or just have more than one like I do. It is easy to use with one hand, easy to drink from and easy to clean.

This is the only leak proof thermos I have ever found. And these can fit in your car and be used as a coffee cup as well. They come in different sizes and colors for his and hers. I had one for quite a few years, and my husband ran off with it because his thermos broke. So, I bought myself another one in a different color. Neither has any leaks!!! And it keeps the coffee hot for a long time. I will never waste my money on another brand again.

I am extremely happy with this product! After doing much research, it was hard to decide between the Stanley, Thermos, and Zojirushi thermos containers. All 3 feature dual-walled vacuum seals, which is critical to maintaining the inner temperature. What kept me away from the Thermos brand was taking apart and cleaning is more trouble than it's was worth. I'm not being picky. You can check the YouTube videos yourself. The issue is the reassembly process for all the parts (there are several). If you do not place things back together just right you're in trouble. I do like the warranty and confidence of longevity using a tried & tested quality name brand such as Thermos.I also liked the Stanley model. It's rugged & durable, and even comes with its traditional cup you can use. The main reason why I didn't pick the Stanley is because the thermos was too large to fit inside my car's drink holder. But like the Thermos brand, I fully trust the name behind the product.So I then decided on the Zojirushi product. They manufacture a few different models of this size, but I chose this one because the stainless steel interior was proven (hint: there are some good YouTube review videos) to maintain the liquid's temperature a hair better than their other versions - including the "coated" version of their newest model. Don't get me wrong... I'm sure the coated version is an EXCELLENT product that should yield exceptional results for hot or cold drinks over a long period of time. The 100% stainless steel interior was only slightly better - keeping coffee a degree or two hotter over a 4-6 hour period. In all cases, it's highly recommended that you prime a thermos with boiling (or very hot) water first before pouring the actual drink inside. Doing this simple step makes a HUGE difference. If you don't, the drink can immediately drop as much as 5 degrees from pouring hot liquid into any container that is room temperature.Let's get into the features I love most:1) QUALITY construction! The thermos is light weight, but has a nice engineered "heft" to it. It's ergonomic in the palm of your hand, and you never feel like you will lose control or the thermos will slip out of your grip.2) The lid is freaking amazing! For one, I like the "double-lock" system. There is a thumb snap that secures the lid in the locked position to prevent opening in the off chance the button is accidentally pressed. When the button is pressed, the lid quietly flips open, but it doesn't just expand to 180 degrees. The spring hinge extends backwards even more to maybe 15-20 additional degrees beyond the 180 point. This means you can drink from the thermos directly without your nose hitting underside of the lid's top. The hinge mechanism also prevents the lid from falling back down to the 180 degree mark; you need to physically move the lid as the subtle "spring" requires enough pressure for it to return back to the 180 degree position. The hinge requires pressure again for it to fold back over into the closed position.3) Everything the hot liquid touches is BPA free! The stainless steel container is 100% safe. The rubber stopper should also be completely safe. There is a plastic spout that is present, but the hot liquid only touches this part while pouring, and is not in constant contact with the hot coffee during storage use - though even that shouldn't be a concern since all parts (including the plastic) are rated BPA free.4) The spout has a flow regulator (both a positive and a negative). The flow regulator makes the thermos great for drinking coffee while driving. You get a nice drinkable flow without worry of a sudden gush landing on your face.5) The cleaning is literally a snap! It's SUPER easy to remove the plastic spout and rinse clean. It pops off easily and only snaps back in one way. There is no way to mistakingly assemble it back together incorrectly like the Thermos. It's a very well engineered system, and takes less than a minute to take apart, clean, and snap back together. The 2 rubber gaskets can also be removed easily and replaced for a more thorough cleaning, but IMO this level of cleaning is only needed periodically. Just snapping off & on the spout piece is more than adequate to rinse any coffee oils away. I do this at least every other day.The areas I didn't like (as much):1) The flow regulation of the spout does make pouring into a cup a slower process. You have to pour slowly and it takes a little longer to fill your cup. You can't modify the flow regulation as it's part of the shape of the air holes with the spout. This wasn't a deal breaker, but is something worth mentioning.2) While the thermos perfectly fits in my hand, it's a bit too lose inside my vehicle's drink holder (your mileage may vary). For my car, a wider bottom would have made a snug fit, but I'm thinking I can figure out an easy solution to overcome this one minor gripe.Bottom line...This Japanese engineered thermos is THE BOMB! For the price, I wouldn't hesitate to buy many as they would make a great Christmas gift.

I've had a bit of an odyssey with thermos tumblers over the past few months. Initially, I tried the budget route since I thought, "it's just a tumbler, it should be pretty hard to go wrong". Realizing I had in fact made a mistake, I went for something a bit more expensive (more expensive than this tumbler), but was still left wanting both at the exorbitant prices a certain brand was charging for covered lids and from their mediocre thermal retention.Which finally brought me here to Zojirushi. Zojirushi is a somewhat well-known brand for rice cookers and other pressurized appliances, so it's only natural that they'd know what they're doing with a vacuum-seal and thermal applications.This thing is basically the holy grail of thermos tumblers. The heat retention is unbelievable. Compared to some of my other tumblers after (anecdotal) testing a couple of times, it regularly stayed ~20+ degrees F hotter than any of the others after being left to sit TWICE as long (the others lost their heat around ~2-3 hours, I gave up waiting on the Zojirushi to cool off after 6 HOURS). I'd go into more detail with some specific testing, but the difference between this tumbler and the others (vs. both a cheap $10 tumbler and a "premium" $35+$12 tumbler) was so drastic that I didn't really see the point.The lid is entirely leak-proof as new. I haven't had it very long, maybe after some wear and tear or being beaten around it might be possible for this to change, but I wouldn't count on it. The design of the lid has multiple gaskets and is enclosed, so there would need to be failure in multiple places for this thing to ever leak. You can try to force it to leak, turn it upside down, shake it around, throw it, whatever you want, but nothing is gonna come out. The lid has a lock for added protection against accidentally opening it in a bag or in some other bad situation.The cap on the lid is exactly what I'd been looking for, an enclosed opening that is covered completely when you're not drinking from it, but also opens enough that it won't get in your way while you drink it. It flips back fully and then locks in place so that you don't have a lid bumping against your nose. The opening itself is large enough for a good flow and also has a second opening for air to ensure a smooth pour. Again, the major plus here for me was that the lid is COMPLETELY sealed and covered. I'm not a fan of drinking from a lid out in public that I can't cover up or protect in some way, this solves that issue extremely well.The ONE thing that must be remembered about this thermos: As long as you take care of it, it will take care of you. You have to hand-wash it. It's not made to be put in the dishwasher or subjected to extreme heat or strong detergents. It's not made to be left soaking in hot water. It's not made to hold certain liquids for extended periods of time, like soups that are high in sodium since it can damage the interior coating. Assuming you use it regularly and always make sure to dump out any leftover coffee/tea/whatever then give it a rinse out it should last virtually forever. Take care of it like you would your stainless steel cooking utensils.Breaking down the lid is easy and simple. The parts of the cap come apart in a pretty self-explanatory manner, and it only takes a few seconds to run some hot water with soap and rinse it all off when you need to clean it.Some final considerations that I'd consider mostly subjective to each buyer:This 16oz version is pretty thin. Personally, this was appealing to me since it spends more time in a backpack side pocket than in a cup holder in a car. It's easier to carry and hold than some of the other, fatter tumblers I've had. There are other versions of this brand that are more or less identical, but are made to fit better in a cup holder. You can find them on Amazon and they cost the same price as this one.The closed lid is probably better suited to an active or on-the-go usage than someone that just wants to keep their coffee hot sitting at their desk. You could just leave it open, but one of the alternative versions with a different lid might be better if that's how you'd typically use it.I really like how it looks. It's simple, clean, and professional. No-nonsense kind of look, especially the stainless design. Some people might want something a little less "stiff" with extra designs. I haven't seen any Zojirushi tumblers that come in patterned designs or with anything like that, unfortunately. You could probably just get a wrap for it instead if you don't like any of the colors.

This mug is the best!The size,12 oz is perfect for my daily needs.Heat retention is great leak proof and the lock works well.I am changing mugs from a Stanley travel mug 16 oz with a trigger.It worked well too but I like this because of the smaller size.I use this to make an Americano,2 nespresso pods plus 2 oz of hot water,no aftertaste.

NO SPILLS and stays hot!!! Lock/release button is directly in front of the lip. If you don't mind that it's a great travel mug.
