I have one- but didn't pay that much for it though since I also work for one of their vendors.
It works quite well, as one would hope for that kind of money, BUT the single largest drawback to it is that it won't handle the smaller filters like the 51040's,51042's and the 51348's. I've made a small piece of steel in the shape of a shallow "V"to take up some of the room so the cutter will reach, but then the filter turns harder because it's not up against the rollers and the "V" likes to slide around. I will someday make something better.
When I made the purchase, I called them up and asked them about what size filters it would handle... They told me about the various aircraft numbers it would cut, which of course meant little me. I told them the diameter in inches of the filters I wanted to cut and they thought it would be okay... Not so much. I'm no airplane enthusiast and they don't mess with autos. Turned out to be a bad combination.
