That's disruptive tech. Very impressive guys.

Could you talk about the most difficult technical challenge you came across? The temperature regulation (i.e. the heart of the pcr machine) seems to me like the toughest part to get right.

I had the luck of working in a couple of well funded research labs, and I wonder if some of the tall prices we see for this type of lab equipment is due to "using someone else's" money for research.

In any case, I'm sure there'll be plenty of cash strapped labs around the world who'll make some science with it.
