Zojirushi Tuff Slim 17-Ounce Stainless-Steel Vacuum Bottle

I just knew I had to write a review on this thermos and let you know how fantastic it is! I've always thought the glass vacuum bottles were best because that's what my mom always bought when I was growing up. I was a little skeptical, but based on the reviews here, I eagerly ordered this little bottle, and it is SO much better than a glass vacuum bottle. My mom and I made coffee early in the morning and it was still hot (a good, drinkable hot--not warmish) over 12 hours later! I do fill it with hot water while my coffee's brewing to heat it up, like you're supposed to do. The little spout pours perfectly and I love the push button--never seen anything like it. The best thermos bottle ever!

I needed a high quality thermos due to my workgroup moving to a building where the on-site food vendor has an insane policy of not allowing patrons to use their own mugs to dispense his decidedly average coffee. (Well, you can pay the he wants as he "doesn't know how big your mug is".)

I read many of the reviews here, and decided the negative reviews were bunk. After receiving the Zojirushi, my opinion of those reviewers giving 1 or 2 stars is that they are either silly, can't read basic instructions, or ignorant of basic physics.

1. The instructions that come with the product CLEARLY state how to clean the unit, including removal and care of the gasket. Read the manual ... it's a whole page long, so yeah, I realize that's a lot to ask.

2. This model is NOT a "sippy cup" -- not sure why someone would complain about a feature that clearly wasn't part of the design. The spout design, however is rather clever and works like a charm...Read more

I came to regard Zojirushi brand due to their leadership position in the bread machine market. I also have much family that use their rice cookers with satisfaction (I still have a Tiger). However, I understand they started with vacuum flasks first. These flasks were invented by Dewar in Scotland but Thermos in Germany patented them and Dewar lost the suit to regain patent rights. Today, Thermos quality is across the board. I'm sure they make some good and some not so good. This Zojirushi isn't the best Japanese craftsmanship, but it's a product outsourced to Thailand. Still, I found it satisfactory. Most importantly, it kept liquid hot.

I preheated it with boiling water, then filled with boiling water. I measured the temperature of the just-filled flask with a Fluke infrared thermometer. It was 175F. This is as hot as practical at my high altitude, higher temperatures would require pressurization. I closed the flask and let it sit upright for 12 hours overnight...Read more
