Most Helpful Review
"It says this thermos is stainless steel. The photos and videos do not show that this bottle has a PTFE non-stick interior. National Institute of health says this coating is toxic. Zojirushi would not accept a return or exchange when I called the company. I would ask them to post the non-stick information clearly so people can make an informed choice. Talking with their customer service supervisor was annoying. I would not order from them again. I have no use for this object, if anyone wants it, let me know. I just wasted 30 dollars."

I got this after watching a video comparing a bunch of other brands and this one was pretty much hands down the best performing in every category, and they're right! While I didn't really check the size, so it was kind of smaller than I expected (my bad), its lightweight, easy to clean, and most importantly it keeps the temperature extremely well. I made some tea after I got it to test this out and I came back to it around two hours later and it was so hot it scalded my tongue. It's a solid investment if you're looking for a new mug!josh robnolte

This is a great travel mug. I can put coffee in it at the start of the trip and many hours later the coffee is still hot. Makes getting a coffee while traveling such a game changer. Love it.daniel j felleman
Keeps hot or cold. Great seal

This cannister really does keep liquid hotter for longer than any other vessel I have found and I've tried most of the main brands including contiguous, thermos, Bubba etc. I use the Zojirushi for blazing hot water (after sitting full all night) to refill my Contigo tea which is no longer hot enough after several hours. If there is a better cannister for retaining hot liquid the longest, I haven't found it.eddie
Good quality and just as described. Holds heat great.

I've used this mug for traveling and it fits perfectly in my backpack water bottle slot. It's ability to retain temperature is AMAZING - seriously it almost seems to defy physics. If you're looking for a good looking water that's high quality and can keep your coffee or tea hot for up to 24 hours, look no further!What Customers Talk About
