I bought this product August 14, 2014 at Aukey Direct, I used only about 30 days, wishing to initiate March 20, 2015 or 7 months after, this diffuser does not work, no light, no smoke, wanting to apply for 1-year warranty with Aukey Direct, it is no longer possible, this product is no longer sold by Aukey, I find it surprising or too much trouble? by cons it is found from another vendor dula beauty like this do not worry, then a board Think before you buy.
