Query: stops working

I liked it when I first got it. Then in less than a year it just will not charge. I only used it a few times. Nothing happens, no lights, nothing blinks when I plug it in. I tried different outlets. Luckily I bought 2 and so, a year and a half later I opened the second one I had, brand new.I plugged it in and NOTHING happened, it will not charge, doesn't work. I spent over $165, what a waste of money. It was not exposed to humidity, kept in a dry closet, constant temp. It is a gamble if it works and charges on, then it helps the acne. If it does not charge or turn on, then it is a just a pretty pink paper weight. Wonder if I could sell the tip, anyone interested?
