I am a private person, 62 years old, male, with a cherry tree, neither versippt still related by Leifheit or Amazon. I was extremely skeptical and had the part sent back by return mail if it would not have worked according to my ideas. - I have to keep him after I've hunted through 3 Bucket cherries in a short time. It just works perfectly. Not quite as fast as in the advertising postulated because cherries not sometimes rerolling or the stone is stuck. But rapidly much faster than with anything else I've tried before: knife, stoner-tongs, hair clips etc. This Entsteiner works cleanly without having juice appreciably in the area herumzuspritzen or squish the cherries. I am convinced of the stoner and would recommend it even friends - but not give. The will itself buy one. :-)) Sönke
