Review on 🕯️ INAROCK Window Candles 12 Pack - Flameless Electric Candle Lights with Remote Timers, Battery Operated Flickering Candle Light. Includes Removable Holders and Suction Cups for Thanksgiving and Christmas Decorations by Daniel Dominguez

My guess is that the person who wrote the very bad one star review didn't realize they had to pry a tiny bit of plastic out of the remote to connect it to the battery . I find it hard to believe that all 12 of his candles didn't work because all of mine worked. They work great and the light is believable. The flicker feature is actually pretty believable from a distance. And you don't need to turn it on, you can just turn on the steady light. It has a dimmer function which seems to work pretty well and I think they're probably just as good for candles that you don't need to plug in. Obviously this saves the hassle of finding cords everywhere and plugging in extension cords. I have a lot of windows and this will be great. And much safer.
