how well does Vogone work

[viva_live_2000]

hi, currently i've searched couple of vocal removing softwares and tried them, none of them seem to give me a result that i want. then i found Vogone, but i don't know how this one works compares to other softwares. and i have to pay $55 for this one. so i kind want to know the quality of this software before i buy it. could some of you, who have used it before, be so nice to give me some feedback about Vogone. i know none of the software can remove vocal completely. but things like if this software works better then others, or worse, or about the same. you know, things like that... thanks a lot guys, waiting for your replies.
