The unit is well made, fits comfortably in your hand. There are included 2 special blades, with this is to peel well when switched off. After switching on you can feel a vibration, but the hoped-swinging motion of the knife has no appreciable effect. Despite the use of a completely new battery, the hoped-peel relief was imperceptible. I appreciate 3% and 97% vibration meter vibration in the hand, the device is good really just like a peeler without motor, or as a vibrator for other purposes, but not as a super motor peeler
With a conventional peeler 1 can achieve the same thing. I would not buy it.
