I thought these looked a little weird with the flat plastic flames that shook as I set up the candles. But once I put batteries in and turn them on, those odd flames flickered really nicely. The pillars are of real wax, and the lighting color was realistic. The remotes are great-- just point at whichever grouping of candles you want to turn on or off and it only impacts that grouping.
These are more expensive than some of the other options. i went with this set because of the variety of sizes, but i'm very pleased and would definitely purchase them again.
I haven't used them long enough to tell how long my batteries will last in them.
