My colleagues were amazed how lazy a single Direction person can be but that he ordered an even touching cup. That was a big plus. The cup should be rinsed in any case, so that the engine will not fix. Cocoa is therefore rather poor. In addition, the rotor base is not 100% tight and now I have tea in the transmission. In addition: The hotter the drink, the leaking is the cup. This means that the motor slowly absorbs water, which then seeps through the bottom of the cup. There it is collected by the battery cover and can eventually short circuit the batteries. Not so cool. I use the cup therefore bottomless. But keeps you so far several weeks (and I work in the IT -> the cup is so much used)
Overall, it was worth buying. But I would pay more if I need a proof. perhaps even Spülmaschienenfeste, could buy version.
