I’ve got two of these (one I lost and later found, and the other I bough during the former’s hiatus) and can confirm. These things are almost too good. I now cool any hot beverage off to ideal drinking temp before putting it in the Zojirushi and set off on my way.

Once I filled one up with coffee in the afternoon (maybe around 4pm) and stuck it in the fridge so I would have cold coffee the next morning. Well 7am rolls around and I open the thing up and the coffee was still fucking hot.

I’ve had hunting trips where I wasn’t able to enjoy my coffee during my sit because it was too hot the entire time.

If I had any complaints it would be that the finish can flake off over time, especially if you put them in the dish washer (yeah yeah yeah I know you’re not supposed to put the main body in the dishwasher but I do occasionally), but it’s just stainless underneath. Throw on some stickers, problem solved.
