Bests & Worsts Reviews from Amazon

I ordered 4 sets of these lights for outdoor decoration. One box had been opened taken out of the box before. Just happens to be the set that doesn't work. At first about one 3rd of the lights were blinking on and off every few minutes...now they don't work at all. Contacted the dealer but was told I would have to deal with Amazon instead. I guess I have to pay to return this item just like somebody had done before and they just shipped it out to me. Not happy!
