Stays on 24-7 when set for 4 hoursSo far so good! We ordered two sets of four in these candles to get two remote controls rather than buying a set of eight with only one remote. We wanted to have one remote on each floor of the house. The remotes are terrific! They measure 3.25" X 1.5" X 0.25" and offer five options: on/off, flicker light, steady light, 4-hour timer, and 8-hour timer. Remotes use a replaceable CR2025 3V lithium battery in an easy access slide compartment. Note that the lights must all be switched on for the remote to work. The remote must actually be pointed directly at each candle to activate it. So, if you have candles in windows in separate rooms you must go into each room to remotely activate each candle. Remotes work from outside, too, at least for first floor windows.The 9" candles come with a red tab sticking out under each "flame". The flame must be unscrewed to remove the tab that sits between the flame portion and the top battery in the AA battery compartment. The candle's switch is at the base of the candle which fits into the plastic silver holder. We ordered the silver base which comes with a candle flame that is more white than yellow. The flame is not nearly as bright as the old electric window candles with incandescent bulbs, but these are readily visible from the street at night.There are two downsides to the candles. One is that we don't see any way that the flame can be replaced when it burns out. The manufacturer does not address this. At the very least, information could be given about a flame life (and thus a candle life) based upon average hours usage per day, like is given for a light bulb. So be aware that the candle is done when the flame portion burns out.The second flaw is that the candle is designed to be stabilized using a provided snap ring that attaches to a suction cup. The problem is that the snap ring will only fit around the top part of the 2-inch silver holder and is too small to fit around the candle itself. So, if you sit the candle on a window sill and also have a wood frame window with wood at the bottom of the window rather than glass, the wood frame of the window stands as tall as the silver base. Thus, the suction cup hits the wood frame, which it will not stick to, and makes no contact with the glass!. We ended up taping the base onto the sill in places where the candle might get knocked over.All in all, for us, the neat remote overcome the candle's flaws and warrants a positive rating.Finally, after ordering battery window candles 3x, i found just the right ones! So easy to use, sturdy construction, no broken parts or dim lights; and the flame color is quite similar to a wax candle flame! not pink or Halloween-looking. and an excellent price, on top of all the other good stuff.I use the candles in my front window as a welcome to my home when it is dark outside. (This is a custom in Sweden that I noticed when I visited some time ago. I liked it so well, I followed suit.) The remote works on the candles individually or sometimes in twos, but some turn off before others. Then I have to reset all of them. That can be a nuisance, but not enough to make me not want to use them. My biggest disappointment was when one bulb burned out. I called the company and the very nice representative said that there were no bulb replacements, but she would see what she could do. Unfortunately, my candles were out of the warranty period, so she was not able to help me, but she was very gracious, which I appreciated. It turned out that I bought another set because I liked them so much. Now I will have spare bulbs if some burn out again.I ordered 3 sets of these candles despite the numerous poor reviews. I have to say, I've had no issues with them so far. Everyone I received worked on initial power up. One batch seemed to have the switch wired backwards so the ON position is actually the OFF position. Not a big deal at all as it's self-evident when you turn the candle on. I lined all 12 up on a table and turned them on with the 8-hour setting. Each one would blink once when a command was received. I then disbursed them to different windows throughout the house. For the last 3 nights, each one comes on and goes off as programmed. I have noticed that the timers vary slightly between candles so they don't all automatically come on at the exact second, but so far they are all on within about a minute of each other - not a problem for me but that drives 4 stars. I'll be interested to see if the variation gets worse over the next month.Purchased 8 candles to place in windows. For the money they will work great. They're bright, they flicker and are the perfect height. 1 candle does not turn off with the timer, it has to be manually turned off. I will return for a replacement.The quick and dirty engineers description and review:Purchased for Christmas. Needed 6 so I ordered what I was looking for. They come in sets of 4 and I needed 6, so I got 2 sets. After taking them out of the box, a collective 3 out of 8 worked.1) Checked power source, 2 AA batteries, included, by replacing with a known good set and no differences were observed. - 5 still dead.2) Referred to owner's manual (single sheet of paper included in packaging) and located a power toggle in concealed location in the base. See Figure 1. Toggle movement resulted in resolution of non-lumination state in 2 of 5 non-functioning units.3) Comparison of known good lights to non-functioning units resulted in the observation of a difference in length of extension of an internal contact wire, see figure 2. Movement of this wire approximately 1 cm toward the bulb opening resulted in resolution of remaining lumination issues.Summary: All 8 lights function with minor modification to the original design/manufacture. Continued quality assurance testing underway to determine longer term robustness of the design system. Figure 3.Received in record time for shipping. Love the timer & remote feature. They have neen working great. Thank you.Remote functions for 6 out of eight candles, one candle does not work at all. They look good and the price is good, but electronics require an upgrade.Looks very nice in my window arrived in a few days fast shipping.
