I can vouch for the qvc candles with the battery and timer. They are good quality, not the type that look like plastic, but real wax and they also give off a faint candle/fresh/vanilla, scent, not at all overpowering, but like a "real" wax candle.
You can turn it on and the candle will then turn on 24 hours later, at the same time. So, 8pm tonight, and then stays on for either 4 or 8 hours (you decide) and the next day they come on again at 8pm.

(I have to say, QVC makes Decorations for the holidays too, with the same technology, one to even goes over the mailbox, no wires, no worries, no running out there, and they twinkle, stay on solid, your choice etc, same principal.)
Well back to the candles, I even purchased them as gifts for my great Auntie and she is 98 and loves them, she uses it as a nightlight/ambiant light and she keeps it by her bathroom door, so helpful for her and she loves the aroma too!
QVC is no questions asked for returns, great options, they are online or you can call or watch their broadcast on tv.
Good Luck!
