When unpacking the device exudes seriousness it weighs a reasonable weight which is reassuring. In use it revelle very effective. the knives are sharpened by 2 or 3 passes. the first time that one sharpens it's longer normal since we must reform the edge. The manual is to bet that remove small burrs that may exist is doing in 2 to 3 passage for a perfect result. The unit is very silent forested except of course when sharpens.
negative: the unit was delivered with an English socket without adapter which forced me to change the outlet.
