These flameless candles are really nice . I bought three for my large pillars and the fit is perfect. Each one came with a remote so I have 3 remotes which will come in handy if I lost one. You only need one remote to control all the candles. So far I haven’t changed the batteries and I’ve had them for over a month. I use it on a 8hr setting. They don’t all come on at the same time nor do they turn off the same time when they’re on the 8 hr setting . It’s usually 20-30 min before the second one will turn on automatically and then another 30 min for the 3rd one to turn on . They will all turn off if I do it manually with the remote . The issue is only while using the automatic setting. The marble look is also nice. The flickering could be a little more intense to make it look more realistic but I really like them .
