Perfect Size
Perfect little size. My husband is a truck driver and he uses it for his coffee creamer. Very well insulated. Keeps it cold all night.

Great for next day Hot coffee
Keeps my coffee hot for over 24 hours. I over heat the coffee first it keeps longer then 24 hours.The only thing is that it holds an oder. Best way to wash it is use bleach soak over night. Great value good size works well and leak resistant.

Good Quality Bottle, But Doesn’t Stay Hot for Full 24 Hours”
The bottle looks great and feels sturdy. It keeps my drinks hot or cold for a good amount of time, definitely works well for daily use. However, it doesn’t really last the full 24 hours as mentioned — more like 10–12 hours for hot water and maybe 15–18 hours for cold. Still, it’s convenient, leakproof, and easy to carry. Overall, a good product but the 24-hour claim is a bit overstated.

Hot for HOURS
Bought these for work to supplement a faulty hot water heater. We would use a few of these and fill with hot water at the beginning of the day. The seal wonderfully and the water stays steaming hot through the entire work day, and fit well in just about any cup holder. Durable as well

It's way too Reliable and I adore it. Thank you.
Keeps things real hot. Try not to put anything too hot in there, I went a little crazy with it...But it won't burn you if you close the lid. Well insulated, easy to clean and can take a beating.

Maintains temp, cap needs redesign
Does keep contents at temperature well. Cap traps water when washed. I've let it sit over the weekend to dry, and when I use it again water still drips out of the cap that must be wiped up. Annoying. My lunchbox has ice packs and water condenses on the outside of the container. This didn't happen on my powdercoated container
