I'm still following this Co. The PPS is much lower now compared to when i bought in, in the spring. It briefly bounced up a couple of times, but fell again just as quickly. Apparently, they have subtantial competition since the Bioshaft Water Treatment System has not been selling like hotcakes in the countries where it's now being marketed.
On the bright side, getting their patent approved in the US is a good thing, especially since the cable news channels are reporting that the Obama administration wants to spend alot of money on infrastructure. ( I hope that includes upgrading many of the country's water treament facilities).
