ZojirushiStainless Steel Mug, 16oz, Smoky Blue

After I bought the Zojirushi 16 ounce tumbler, I gave four others away. They each had flaws: too huge and unwieldy to carry, required two handed operation, difficult to fill and clean, didn’t fit into cup holders, or simply ugly.This one is perfect in every way for my needs.This has a simple pop lid that locks and is absolutely leak proof. It carries a reasonable amount of water. I don’t need to carry my daily water supply on me at all times. I live in civilization and have adequate water sources available to me.This tumbler doesn’t spill water when you screw on the lid, has a mouth just wide enough for ice cubes though I have to squeeze a plastic cup filled with ice to get them in there, and it’s easy to clean with just a regular bottle brush and I can see inside.I’ve had other tumblers with better insulation that kept water colder but I do still have ice the next morning if I fill it at night with this one.I use this tumbler for iced matcha throughout the day and it’s small enough to carry in my bags and take to the gym.Also the drinking experience is an absolute pleasure. It’s vented and you don’t have to unhinge your neck to tip the water into your mouth. Also makes a pleasant babbling brook sound when you drink.The color is a subtle, neutral shimmer bronze gold and goes with everything I wear, not that I try to match outfit and tumbler choices.If I was to lose this tumbler I would immediately replace it.

Keeps my Chai hot for over 5 hours, and I mean hot and not warm.My only complaint is the lack of sizing. The 16oz is just a little small for my use. I’d love it they made larger sizes available.Very easy to clean the top and its parts.Drinking is fine, but wish the opening piece was not directly in front of the sipping hole.Got the gold, nice brushed color, not brassy looking.This is by far my best hot travel tumbler yet.Why did you pick this product vs others?:Length of heat retaining property, ease of washing the capInsulating capacity:Lasts well over 5 hours keeping liquid Hot, not warmEase of opening:Could be a little smoother, assume overtime it will ‘soften up’ the push button

Very cute and holds the perfect amount of water during my work day. The bottle nicely fits my car's cup holder. It's my favorite and I would highly recommend it to anyone who wants to avoid spilling water by using the lock. Super easy to clean and enjoy how the breather hole allows water to flow out of it. I dropped this right after getting it and it didn't even cause a dent, very durable.

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.
