THERMOS Stainless King Vacuum-Insulated Beverage Bottle, 40 Ounce, Matte Stainless Steel

Is simply outstanding. Its vacuum insulation truly delivers: it keeps drinks cold for hours and coffee hot almost the entire day. I’ve used it for travel, at the office, and even outdoors, and it always maintains the perfect temperature.The stainless steel design is sturdy, durable, and also looks elegant. The size is great—large enough to hold plenty of liquid without being too bulky. I also love that the lid doubles as a cup, which makes it even more practical.This is a reliable, high-quality bottle that is absolutely worth the investment. Highly recommended for anyone who wants to keep their drinks at the perfect temperature for hours!

It great to keep my water hot for a day and a half. And the pour hole on the side gives it the edge. The quality is great. Love the design and it's easy to clean and the size is great. I also ve the color

Excellent at keeping liquids hot or cold for long periods of time, I use for yerba mate and tea and it keeps my water hot for multiple days if I don't use it all up before then, longest so far I've tested is 3 days but I'm sure it can go longer.The stopper is also very nice and good quality with no leaking whatsoever, and the functionality of the pouring mechanism is 1,000 times better than the Stanley ones which is also a huge upside to THERMOS in comparison also with the more affordable price point.I have both a Stanley and THERMOS products and I find myself using the THERMOS much more often. Not knocking Stanley though they're still very good vacuum bottles as well.The handle isn't quite as stiff as the Stanley equivalent but still functions the same and isn't an issue at all.Very excellent and highly recommended.

Keeps water cold and coffee hot like intended. The color was described as "midnight blue" but looks solid black to me in almost all lighting. The pour spout works great. My last thermos lasted 14 years before it was slung off my truck at 40 mph (that one still holds liquid but I think the vacuum seal is broken). I'm sure this one will last just as long.

I really like this mug—it’s been super handy for preparing formula for my baby. It keeps water hot for hours, and the handle is comfortable to hold. I’m giving it 4 stars because opening and closing the lid takes a bit more time than I’d like. Overall, it works well and does what I need.

I should’ve gotten this a long time ago. It would’ve saved me a lot of money. My coffee stays hot after almost 8 sometimes nine hours. I take it to work with me every day. I take it to church. I have my coffee with me all the time. It’s a great great product, but it’s also been around a very long time.

Keeps my coffee piping hot for the whole 8 hour shift. Easy to pack away in a bag . Strong materials, doesn't get banged up easily. Holds 2.5 coffee mugs for me. Love it!

Dad said he wanted a real thermos like when he was a kid. something to take to the lake or on road trips. not sure where the idea came from but he said he wanted it so I got it for him. This thing is really big and easy to carry with the handle. Holds alot, hot or cold. love the spout feature. Less chance of spilling. The read color just makes it look really nice.
