Very good
I used this bottle for about 6 months during my travels and I have no complain.
The bottle is composed of bottle, cap and cap cover which can be used as glass to drink.
Based on my experience it can keep the drink hot/warm for at least 24 hours.
Recommended as an isothermal bottle to keep in the car or in the tent while camping close to the car.
Too big and heavy in my opinion to be carried in the backpack unless you are hiking with a group of people and sharing the load.
Overall a nice product, no complaints.
