Query: How did this get such great reviews?

This is one of the worst sharpeners I've ever used. Just about any pressure at all stalls the motor, so it takes a lot of patience to sharpen any knife, and in my opinion a novice with a stone can do a better job. As a matter of fact I got one of those tri stone sharpeners here and was able to do a better job on a knife in less time. I also have one of those very simple sharpeners that you just scrape down the blade and that does a better job in less time.
