The problem with this device is there is absolutely no "precision" in the mechanism that adjusts the file angle. I have a similar device (Swix Xactor II - http://www.reliableracing.com/detail...&category=2000
) that uses the rotating knob to set the angle. The problem is that there is no exact "notch" for the angle that is set (at least on the Xactor). There's no way to ensure that you are setting the device to the precise same file angle every time and the knob can be accidentally rotated. These multi-tuners are just not produced with the same level of quality as the traditional hand tools from SVST, Toko, and Swix.
You might be able to get away with this thing for side edge filing/polishing (since for recreational use side edge angles aren't quite as performance impacting if you're slightly off), but for base bevel setting -ACK! I wouldn't go near my base bevels with a device without sufficient precision. And if you have super sidecut skis (especially Atomic Metrons) you must use a base bevel guide that spans the entire ski width (Toko World Cup) to ensure that the normal concavity of the base doesn't screw up the base bevel angle (there's lots of posts about this issue).
Please don't screw up your skis with this thing. Keep it away from your base edges.
