Lynda, you are one of our Testimonials for Vogone! You clearly continue to do your homework!
As verynewbie has clearly stated, Luminosity is "too good to be true". They do NOT own or develop any products. These products are from other companies, and most are free elsewhere. That should give you a clear understanding what their "business model" is.
Buyer Beware!
For others who read this Thread, MTU has a money back guarantee on our products should you wish to try Vogone. You might want to

There is no vocal eliminator/reducer that will remove or even reduce the vocals of every song. Please read our "warnings" on our sales page so you know before buying. Some folks think the resulting, devocalized song will sound as if the original recording studio did a remix without the vocal. That will never happen. The question is how much of the music is left behind when the vocals are removed. That is where MTU has gone beyond the norm. We allow you - in real time while listening - to adjust how much low frequencies and high frequencies of the MUSIC are retained. By leaving a very slight amount of vocal frequencies in, you can make a tremendious change in the overall musicality of the song.
