Query: Should've heeded the negative reviews

I've had this sharpener for >6 months now and am really disappointed with it, mainly because it's hyped as such an easy system AND costs $50 simoleons. I've spent hours of practice trying to get a sharp edge on multiple different knives -- I've faithfully watched the video and carefully followed the manual - nice easy, consistent hand motions, straight-up & down against the sides of the "V". While some knives took a fine edge OK - though NEVER killer sharp - others were slightly worse for it. And the bit in the video where the guy easily slices paper with all manner of his newly sharpened knives: in your dreams, Bucko! In the end, I've gotten more predictable results with my Arkansas stone, or - God save my knives - with a fine-grade diamond sharpening rod. Consider the other negative reviews on this system before you pull the trigger. I wish I'd gone for a different sharpening solution.
