Product review (1 stars): Amazon is NOT AN AUTHORIZED DEALER.
I have had nothing but problems with this appliance. When I first got it, it seemed to work great, ozone smell etc. After 2 months, no more ozone smell and after another 2 months no more bubbles regardless of how low I turned the flow on my faucet. I contacted the manufacturer and was told that Amazon is NOT AN AUTHORIZED DEALER and the appliances sold through the various sellers at amazon would not be covered. They "did me a favor" and "repaired" the appliance after making me ship the whole thing to them at my expense. It seemed to work for all of 3 weeks and is now fully broken AGAIN. The blue light comes on but no bubbles. My water is of god quality and filtered. This was a complete waste of my money. I am not sending this thing back again just to have it work for less than 3 weeks. My advice, don't waste your money.
