I am very pleased with this bottle. While not the cheapest, but for me is the best vacuum flask. My old vacuum flask had a button on the lock, by pressing this button comes out the liquid. But that's not tight, my backpack was still wet from the tea ... At last a perfect flask of Alfi. Total simple and robust, all I need.
++ Super tight ++ Easy to use, with no magic to the cap ++ The double cup is a good idea ++ Easy to clean, the inner steel surface is extremely smooth ++ Unbreakable ++ Keeps the heat long (at work 7:00 to 17:00 no noticeable cooling in hot tea)
