Query: Calibration is the key - a chick magnet

I bought a Zoj V20, and, since it works great, I give it five stars. I bought one for a friend, and, since she liked making bread by hand, for her, I would rate it one star.Conclusion: any piece of machinery has pluses and minuses, even a simple egg timer takes practice before you can calibrate it and know how to use it just right. And you cannot beat making bread, yogurt, beer manually by hand from scratch.Really this is a chick magnet type piece of equipment, to show, if you are a bachelor, that you have the inclination to eat healthy.
