Negatives: The unit is very noisy, the Fensehen you can not use it for example (!). And the hand that holds it is, more than anything else massaged, it is very unpleasant. This applies to use with or without handle.
I'm not sure if the volume and the strong vibrations on the hand are normal or I caught a Monday device. In any case, the device is therefore hardly ever used, and therefore only brief 3 stars.
By the way the device was probably already at least once sent back, as you could see the signs of wear, so I am apparently not alone with my Meunung ...
