The Chef's Choice EdgeSelect 120 in not a good buy!  I have owned two of them, and neither lasted over one year.  They sharpen really well for about 6 months and then gradually lose their sharpening ability.  After one year, both of mine actually made my knives duller, and I use top of the line Henckels knives.  If you buy one of these, you'd better save your receipt because you'll need it.  They have a three year warranty, but you'll need your receipt or it will cost you $45 plus shipping to refurbish one.  You'll still pay shipping even with a receipt.  My advice is to buy a good diamond coated sharpening steel, which is better for you knives and will last a lifetime.  That will be my next purchase as my second Chef's Choice sharpener hits the dumpster.
