Ozitech Knife Sharpener

I generally take my knives once a year or so to Northwestern Cutlery (mentioned on several lth threads). However, I just saw an infomercial for the ozitech knife sharpener and it seems pretty interesting. There are a bunch of reviews for it on amazon . My thought (just by reading a few of the negative reviews and remembering that quick fixes usually are just that) is that it's probably a really really good honing/sharpening steel, and maybe not much more. That's just speculation though, being I haven't ever actually tried one.

The ultimate question is, what does lth think? Anyone here actually have or tried one?
