ZojirushiStainless Steel Travel Mug, 12-Ounce/0.36-Liter, Black

I own both this version and the flip-top version of this. They both keep the temperature of the contents quite well; however this one has less parts to keep clean and is easier to clean. Also, if you transport soups in these you're more likely to store chunky soups in this one. While you can unscrew the flip-top one too, this one comes with a mouth-friendly plastic piece that covers the top metal edge of the container.This is a 2-piece design, when you want to drink out of it you will need to screw the top. This means you have to hold (or put down somewhere) the top while you consume. In contrast the flip-top you just flip it open and the top stays attached to the container. But then as for the flip-top I found that I was hitting my nose right on the part of the top that was covering the hole to the container and since it always had a drop of liquid on it always wound up on my nose unless I either tip my head back further or suck on the top (which in of itself felt weird to do). Anyways back to the 2-piece product... its opening is relatively the same size as a flute-type glass (think champagne), which tends to make your head tilt back since the far edge will hit your nose.If you're washing the top just before filling it up be sure to shake the excess water out of the top or it may appear to leak but not really it's just excess water coming out from the other side of the outer part of the top. If you aren't Japanese about keeping your mug clean you may be giving a chance for it to become gummed-up and gross. If you don't abuse it during use the seals will last long enough to just buy another mug when they wear out, years down the road.Look for the Zojirushi logo and quality control sticker on the bottom. The inside of the mug is highly polished as well. Don't accept any substitute.

Put hot water in it before I go to sleep. 10 gotta late when I wake up, it is still warm. Great quality and easy to clean. I love talking it with me when I travel.

I've had this mug for 18 months and use it every day. It does an incredible job of keeping coffee hot; after four hours it can still be too hot. And it is remarkably slim, I had to measure the quantity it holds to believe it has the same capacity of my old bulky mug. So: great coffee mug.Recently, though, it has started to leak. Not through the seal where the lid attaches, but through the lid itself. The lid is made up of three parts, for reasons I've never understood. There's the screw-on section (the largest part), a removable seal arrangement, and a cap that clips on top. Perhaps it's to facilitate cleaning? It seemed needlessly complex when I bought it, and still does. It also looked like a source of probable leaks, which has turned out to be the case.So now after a year, the seals to the cap have worn a bit. When I screw the lid on, the increased air pressure inside forces coffee through the seals and into the voids within the cap. From there, it slowly leaks out and on to my hand and clothing. Wiping it clean doesn't work, as it keeps coming out. I have to disassemble the top and mop up the coffee in there, every time I use it.If only they'd made the top in one part, the mug would not leak, because the 'primary' seal (the thread where the lid screws on) is fine. You could still clean the top by immersing it in water. But the needlessly complex three-part lid is the weakness.

As always expect this brand really do deliver the best quality product: water bottle. I use it year round. This is my 3rd one. I have a pink, hot pink and black one in different sizes. Keep content warm up to 4 hours outside at 34 F without loosing any heat. Cold brew usually 5 hours in hot summer day. Fits into any car cup holders very universal for mommies.

I love this travel mug. It has a smooth matte exterior. Easy to hold, as it isn't too big, and it holds a good bit of liquid. I bought this for my boyfriend after having gotten a different one from zojirushi which he kept stealing!It keeps his tea, coffee, and cocoa hot for hours. Doesn't leak, and has that little nifty plastic ring to keep your lips from being burned on the metal.Only thing is, it doesn't come with a tea strainer, but that's ok. It's still an awesome mug.

Wife had a stainless steel one before we married that was 5 years ago and it still works as it should. I decided to buy another one since we have children now and it has helped keep our infants water warm.

First off, I've used other Zojirushi products & have typically been a fan of their well insulated thermos collection and food jars. Overall this company makes good (not cheap), durable products. We had to replace a couple of our damaged travel mugs & this one was on sale. I get why now. There are too many components that only serve the function of keeping your beverage hot/cold, plus there's no flip-top lid to drink out of. Instead, you have to unscrew the head piece and drink from the canister (think of a slim Hydroflask). It's confusing because the head piece is composed of a lid of its own. It opens up to what appears to be a mouth piece and you'd think you could sip from the travel mug from there but you can't. Everything remains sealed in until you unscrew the head piece itself. It's not well explanatory in the enclosed instructions as the text was all in Japanese and there was no English translation provided. Considering this is a first of a handful of purchases I've made from this company, I'm going to let this one slide. But I do recommend looking into their other travel mugs first.
