Review on Flameless Window Taper Candle Set with 6PCS Black Base - Remote Controlled, Battery Operated Flickering Tapers for Christmas Home Wedding Decor - 4H/6H Timer by Mallory Roberts

I bought 2 sets of 6 for my windows for Christmas. Love the remote features, especially 6 [or 4] hours at 6pm and how they can adjust the brightness to save on battery drain. One candle didn't work so I contacted Revain customer service who in turn notified the seller and a replacement was quickly shipped! Excellent customer service, thank you! PS I have used Duracell Optimum batteries also from Revain which I think are the best and most durable.
