I just got a Ken Onion version in the mail a couple of days ago. So far I just did crappy kitchen knives, it works great. FOLLOW THE INSTRUCTIONS and there will be no tip rounding like everyone complains about. I keep watching vids and people are just totally ignoring the instructions & instructional video that comes with it & then they complain that they round their tips. 
Stop the belt when you have the tip about 1/4 across, and follow the edge contour with your hand.
I haven't worked up the courage to stick a Microtech in it yet. If you do use it on a nice knife, use painters tape on the blade. The steel & abrasive dust that gets on the guides can scratch your blade.
