Review on Stanley Classic Trigger Action Travel Mug - 12, 16, 20 oz – Hot & Cold Thermos – Double Wall Vacuum Insulated Tumbler for Coffee, Tea, and Drinks – Stainless-Steel, BPA Free by Anson Shao ᠌

It's a thermo mug, not a thermos. If you pour boiling water, then after a couple of hours it is already comfortable to drink it directly from this drinking hole and it almost does not burn. In general, more or less 2-3 hours is enough for a maximum. Different pros: - Style! Very beautiful, I would say - an iPhone in the world of thermoses! - Light - Compact - Water does not spill - Easy to drink and pour from With its cons. It does not keep heat for a very long time, since the upper steel part takes the temperature onto itself and it gets very hot, but for such a small volume and for my personal purposes, this is not at all critical.
