I bought four sets of these candles about a month ago. 25 of them otherwise known as four do not work. I’ve done everything to make them work per instructions but they’re useless. I was far better with my 40-year-old electric windows in the candles. I’m not sure I will trust Wayfair as a representative of products anymore. The last thing I want do is ship these back and go to that kind of trouble when I paid good money for them. If I could give them no stars, I would. ￼
