I love the water unit and it has been the best water and I enjoy the health benefits that we are getting from the machine, that never got any energy from water until I got this machine after first going through the detox.

Hi Farida, Thank you for the review and the helpful information on portability. Blessings, Cosan/USA
I’m fortunate to live close to the company/warehouse and I always do a walk-in when I need something. In my opinion, The Companys staff are very intelligent and understands the very atom of the product they offer. This is one of very few companies that I never feel like I’m being “sold”, rather, they educate. I like my Alkaline water a lot and the price was perfect.
