I have electric window candles in all of my windows except for 3 in my upstairs where there are no electrical outlets. I ordered these so I could have a candle in each window. From the outside you can't tell the difference and even though you can tell on the inside, these are windows that most people who come to my home don't see.  They were easy to set up and the quality is good for the price. The only thing I would change is that not every window is alike and because of the "lip" at the bottom of my windows, I can't have the base actually sit on my windowsill....so there is about a 2 inch space between the base and the sill. They are behind sheer curtains so it doesn't really matter for me, but it may matter for others. I also wish you could have the option of buying a single candle in addition to packs of two. I only needed three but had to buy 4.
