When Fantom was the new vacuum, I signed my vac shop up to be a Fantom Warranty Center, mostly so I could order repair parts. The Lightning had just come out. I remember how mad people were at their Fantoms, constantly breaking down. Each model had its own problems, many of them caused by cheap construction and materials. The Lightening model was particularly problematic.
I have noticed that you've shied away from actually saying your going to be creating (designing) a new model Fantom, and will have it go into production for sale to the public. That's a huge gamble of millions of dollars - but a gamble it is. Failure is the norm.
You might want to take a minute to read James Dyson's autobiography "Against The Odds". It details the HUGE struggle to get the Dyson into production, it also details how he was screwed by Amway. Remember, the beloved Fantom was a Dyson designed product, manufactured under License by Iona. Good reading.
