He holds long enough warm or cold, is completely sealed, highly robust and practical to use. The 360-degree drinking way I find inszwischen very pleasant. Subjectively, I also feel that the closure the risk of burns if hot drinks softens slightly, as when drinking perhaps a little more air comes to the amount consumed. Measured I did not.
Above all, the tightness is important to me because I transport the cup adjacent to documents and laptop. Even if the bag tips over or is wrong - and thus also the cup - I did not detect a leak. He keeps as close as a thermos. This holds true as well for the Alfi mug.
The only downside I could find during Emsa at all is that the difference between open and closed state is not immediately obvious. One must therefore ensure that it closes off the cup after use. Here it is already happened to me that I have opened inadvertently packed the better the side pocket of the bag. That was clearly my mistake you can commit but easier by the construction of the shutter (central Druckknof which must be pressed down and there locks) as for example when Alfi Mug (Druckknof side outside), from which one can only drink if you hold down the button. However, this is considerably more uncomfortable than the lock solution of Emsa cup while drinking. It takes in the case of Alfi in a full beaker due to design even more force to operate the Druckknop. When driving a car, for example, I feel that uncomfortable.
In the dishwasher to EMSA-cup can be cleaned easily. The stainless steel design is sufficiently robust. After I had also painted models from other manufacturers in use, I can only generally be selected in such cups the unpainted versions because one quickly sees the scratches and falls painted cups, so they at least become unsightly with me soon. Stainless forgive visually more here.
Total EMSA tumbler is a nearly perfect thermal mug for everyday use, I will buy more immediately in case of loss for me. It is absolutely worth the money.
