The Chinese seller of this item is trustworthy! The product meets the specified properties and hydrogen water is produced in about 7-8 minutes. When fully charged, produce 6 to 7 glasses of hydrogen water before the battery dies. Charging takes about 1 hour. The supplier delivered the goods from China to the US east coast within 2 weeks. What I really like about this offering from this vendor is the analytical meter that comes with the product. This gave me the certainty that the money spent was worth it. I also used this meter to test the quality of alkaline water made by a $500 Chinese-made machine from a dubious supplier, which turned out to be a waste of hard-earned money.
