I can very well differentiate BFL from SP-Tech and have said that SP-Tech have an amazing product with SP10.

If each chip pulls double the wattage that it was supposed to, do you think they made sure that the copper layers in the PCB can handle the extra load? Can the rest of the components handle the extra load?

The may not need "Two Weeks" as BFL did to redesign a PCB board 50 times, but it has not been ruled out.
