have the device for several months now and have been using it mostly on the weekends. That is to say that it was not subjected to intensive loads. But so far I am very satisfied with the device, the handling and the result. Use it always for 1.5% milk and the foam is really great! One star deduction is available for the cleaning, which is easy to be true, however, to note that under no circumstances water may come to the contacts on the lid and handle, makes me a little unrelaxed. But after all, has also previously worked without problems. So whining at a high level!
