[4] Despite several faults, Biro and his manager Ed Cohen showed it to Wakeman who was so impressed by the endless loop feature that he turned to them and stated: "How would you like to make some money with this thing?"

Wakeman's factory and rehearsal facility run by business partner and CEO Peter Robinson in High Wycombe, England.
[9] Over 1000 advance orders (totaling over one million dollars in paper) came in from charting major music artists such as John Lennon, Paul McCartney, Keith Emerson, Rod Argent of The Zombies, John Paul Jones of Led Zeppelin, Roger Whittaker, Captain and Tennille, Rod Stewart, Patrick Moraz of the Moody Blues, Uriah Heep, The Beach Boys, Vangelis, Gary Wright, Chicago, Tangerine Dream, The Faces, Klaus Schulze, Dudley Moore, Synergy, and Elton John.

Its' association with art and progressive rock as opposed to the emerging new wave and punk music movements at that time was also a possible marketing challenge.
This rendered the Birotron to become the rarest instrument in the world to be used on albums, tours, and a top charting hit single before its' sudden disappearance within the music industry.
