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 Minoru Koshida ᠌

What is the quality of a thermal mug: 1. the quality of the steel of the flask so that the product does not oxidize and it is not necessary to drink amalgam or metal oxides every time 2. Heat preservation time 3. Cover collapsible or not Here is the foldable lid. Made of two parts, it will be very convenient to wash. My previous thermo mug had a non-collapsible lid, you can wash its figs. Some kind of crap started up there (either a fungus, or some kind of microorganism, or some kind of mold, don’t understand what), and I get a sore throat from it and my voice disappears, so Stanley has a collapsible lid as a plus It will not keep heat for a long time, the lid heats up, which means that heat escapes. My previous one did not get so warm The quality of the steel flasks can not yet be assessed. At one of my thermoses, the metal oxidized green tea into some kind of dark barmatukha. They could, of course, cover the inside of the flask with Teflon or some kind of ceramics, it is not clear why not a single manufacturer has thought of this before. Stanley has a series of ceramics, but there seems to be only a stone case Well, the smell - it’s impossible to drink coffee, tea too, as if you were licking your hands at a car mechanic
