Personally, I think they will need to sell roughly 1700 units per month to break even. That is allowing for a 50% margin on the product. Also, from memory the trailing income doesnt start for 12 months after they have purchased the device?

$299 per device
$150 margin

1700 x $150 = $255,000 per month
$765,000 per quarter

R&D reimbursement - $250,000 per quarter ($1,000,000 annual)

$765,000 + $255,000 = $1,020,000 per quarter to cover costs.

Now in 6 months time if they have say 1000-1500 users then the following year we will be earning another $1500 per week. Allowing for a 50% drop out would make it $750 per week or another $35,000 per year. The higher the number the more it compounds.

Hopefully they will kick some major goals in the US when they launch later this month as the pericoach is only $233US if pricing is in Aussie dollars there. If it is higher than even better for the bottom line.
