Bests & Worsts Reviews from Amazon

I initially purchased 3 Moonrays after reading the good reviews on them. They are very pretty and worked well at the beginning. After about a week, one of them took a dive, only staying lit for a few hours. I contacted the company directly and didn't get much relief. However, since I was initally pleased, I had in the mean time ordered and additional 6 for gifts, but then decided I didn't want to give them in case my problem wasn't an isolated one. Sure enough, on the second order, one of them has also taken a dive, brely working, and then only for a few hours. As stated to the manufacturer, they are all together, so they are charged and viewed under the same conditions.
