Among the deficiencies:
The inner values are cheaply. Due to the defect are used carbon brushes of the motor. The motor now runs no longer, unless it is given by the axis rotate jumpstart. Then he runs though, but only on visible smoke and this very typical smell of ozone and slow abfackelnden contacts, which is logical, since the carbon brushes are used up. Given the few minutes of operation of the device unfortunately a joke.
The contact to the motor is incidentally made on a micro switch, which in turn is completely overloaded and accordingly strongly heated because here drops a not inconsiderable part of the excitement. No wonder, since such micro switches are designed for currents in the milliampere range and are not absolute for use, as it occurs in this unit.
Overall, just annoying, a pure single-use product if you dare the thing two or three times to use during the day.
