I had to write positive reviews before this one or I would have been terminated from the case study which I was suppose to be compensated for. I now have a $12,000 loan that I have to pay off. The water only produces 2.5ppm hydrogen not the 5-9 ppm they advertised. There was no mention of filter replacement needed after 8 months and no way to get one. Many customers dealing with mold in their machines. Be warned. Read all the other negative reviews. They are true. Check out the CNBC article about Trusii's case study scam. Customer service is horrible. The molecular hydrogen institute does not recommend Trusii. Dont be fooled like I was.
