I've spent years looking for a thermo mugs, the fact which can keep the beverage temperature for longer than 30 minutes, leakage protection, practical drinking spout, easy and thorough cleaning. the cup from this company fulfills all these faktoren.es is great, then you can disassemble the cover to wash into several parts, if a drink accidentally but times longer stays in the cup, you can be sure that no mold crust hidden under Mouthpiece , the material takes smells not as fast as in other cups of the case. Also, riiiiiiesenplus: drinks remain eeeeeewig warm, two hours very hot as soon as the level decreases cools the drink faster, but also by an estimated 5 hour you can still warm drinks sprechen.negativkritik there is not mine.
