I have the electric true Cut and love it. I think many people are unsuccessful with it because they don't wipe off the dirty oil and put a drop of clean oil on each side of the sharpening stones every time they rotate the sharpener. Dirty oil (oil with tiny bits of metal in it from sharpening) fouls the stone with embedded bits of metal, making sharpening impossible. You have to wipe off the dirty oil on the stone, put a drop of clean oil on it and rub that into the stone with your finger to dislodge the metal bits, wipe that off, then re-oil the clean stone with every rotation of the sharpener, on each and every stone surface. Do that and you'll have success.
