Price / performance ratio appropriate

The device works well made, nothing creaks or cracks. The rotary mechanism for the desired length is working properly and makes a stable impression. The device is also very quiet, but has nevertheless enough power.
Unfortunately, no mains operation is possible because only one charging station is included. But no such connection is present in any case for a cable.
Even a light for the state of charge does not exist, which is why you will not be notified when your battery is low, even when it is fully charged.
Nevertheless, these small deficits are justifiable, because you really get a useful device for his money!
