Bests & Worsts Reviews from Amazon

I bought two of these units. The first arrived not working. Amazon refunded the money as quickly. The second unit worked for a little over two months. I contacted the seller, Organic Aromas, at first the seller seemed to be willing to replace the unit, then contact stopped. I am highly disappointed. I really enjoyed using the unit. I am now have a unit that I cannot use, what a waste of money.
