The thing is, you're not even talking high volume at this stage. It's still relatively small production runs. They could have done their earlier products through a US based fabrication shop to get the cash flowing, then switched to a Chinese one once they'd got a steady income and could work through these hassles.
Given all of the Chinese electronics manufacturing, would the required components even be available in the US? I assume many if not all of the individual components would also be made in China... so maybe it's just more convenient (in addition to cheaper) to have the entire product made there?
