We worked with Bioking for over a year, found our investors for $25 million USD, we needed a small sample of algae oil so that we can have a 3rd party test it for sustainability and reliability in biodiesel. Week after week for months they kept promising us a 100ml sample and even told us they have send it and week after week we keep calling back, still no sample. You would think a company selling this equipment would be able to provide a sample if they want millions of dollars from you. We couldn't even get in touch with their CEO or management, the only help you get is the salespeople who will promise you the world. Stay away this scam it is expensive and it will only hurt your company's reputation. Good luck out there, if you have equipment that work or samples for me, we will consider all options except Bioking
