Question: How to set timer
Document: These candles are so perfect I keep them on my patio and set to timer and once night time hits there glowing, love it. Going to get more :)
I love these LED flameless timer candles! I set the timer so they come on when the sun sets, and in 5 hours they turn off automatically. The ambiance is gorgeous. I was also very surprised, yet pleased that the batteries came with them.
This set of candles with timers is just great. I set them up for Christmas decorating. But I'm continuing to use them, as I like to have winter decorations out, like snowmen. They look so nice and add just that little bit of light in a room or hallway. The timer means I don't even have to think about turning them on or off. The scent is subtle, and does wear off.
This is the second set of these we have purchased. The first set we bought close to a year ago and just love them, so we bought a second set so we could put them in more rooms. They are quite pretty to look at - almost mesmerizing. The seem very durable and we have not yet had to replace any batteries. They are scented and the scent seems to last quite long, although it does diminish over time, of course. But what we love the most is the timer function, that way we do not have to worry about turning them off before we got to bed.
Brought these candles to a friend as part of a house warming gift. They look beautiful on her mantle . I have many flameless candles of my own that cost more than the Westinghouse set  and lack the vanilla scent. Good value.
I love these. They are realistic looking and made of real wax that has a pleasant faint vanilla scent. Very simple to use, just turn them on for automatic on/off. Just figure out when you'd like them to turn off and set them 5 hours before that (so turn them on at 7pm to go off at midnight) or just turn them on and off as you use them. I bought 2 sets and I would buy them again!
Buy these candles! I have had them for 5 weeks now and have not had to change the batteries, and the timers are accurate and don't go slow or fast. These also only require two AA batteries. The other set I bought took 4 AA batteries and I was changing them every three weeks, and the timers were waaaaay fast. I wish I could remember what brand they were so I could tell you not to buy them, but BUY THESE!! They are a nice creamy shade of ivory when not light, and they flicker gently when they are on.
Because 1 out of the four does not work properly, the timer does not work that is why it go this rating.
Quite bright compared to other flame-less candles I have owned. LOVE the timer feature. Will be purchasing more in the future.
I like these very much, but the timer on only two of them actually works. I see now that you can buy them most anywhere, so if I want more I will just get them locally.
