Love these candles!  They're a bit on the dimmer side and yellowish, hopefully they have another version that's a little brighter / whiter.  But the flicker is very gentle and not distracting like some other flameless candles.  We have used the timer function and that's been mostly great.  The flash when you first press the "6hr" on the remote to indicate they're synched.  The first night 2 stayed on after the others turned off, but the kids had been playing with them so I wasn't sure they hadn't flicked the switches on the bottom or something.  The second night one stayed on.  As soon as I hit "off" on the remote it was fine though.  Will see how they do with additional days.
