So first, I ordered two boxed of the candles and both arrived on time. Perfect! But, two were defective/broken on arrival. I emailed the support address included with the product and they responded very quickly, and had a replacement BOX sent out shortly thereafter. The second box arrived and all work great. You can't beat t he service.As for the candles themselves, they work just as advertised. I have these in all of my windows for the holiday season. I have them set with the enclosed remote to run for 8 hrs each night and they all work great. As for the window mount/suction cup clips: do NOT attach them to the candles themselves. They are wax, and the clip will damage them. Instead, the clip WILL fit around the enclosed metallic-coated bases just fine and that is exactly what I did. They are sturdy and secure in my window - even when my knuckle-headed teenager opened the window. Stayed in place. Very happy with my purchase.These candles are solid, have a real wax look and feel, and a warm white light. I have them in both my downstairs and upstairs windows (7 total). They were easy to program with a single remote. I put them together and them placed them all on one table, then programmed them to go on at a particular time, and to go off 8 hours later. I then placed them in the windows. They go on and off every night at the exact same time, so I no longer use the remote now that they are set for the holiday season. The remote allows for 2, 4, 6, or 8 hours on, and it also allows for a steady light or a flicker light. The suction cups did not stick to my vinyl window frames, but I don't need them anyway. The candle bases are good enough, and the candles don't fall over easily.The candles and the silver base are pretty, but there are a few issue's I ran in to, the holders don't really hold the candles, they fall out or just don't go in, the remote didn't work right out of the box, I removed and replaced the battery and it still didn't work so if you want to turn off the candles you have to take the batteries out in order not to have them go dead, and also the bottom where you put the batteries in is really not very well made and it feels like when you turn it to take out the batteries out that its just gonna snap off. I should have looked around for a better deal.One candle out of twelve does not work with the remote. The other eleven work perfectly. The candles feel like wax, the flames flicker and the length of time on the timers is variable. I would recommend this product.I think these candles are a great buy. I love that the flame is a warm white, but not yellow. There is an option to choose a steady flame or a flickering flame.My only disappointment is, since I have 8 windows, that I can’t purchase a lesser number than 6.They work. Flame is dim, not bright at all, but with batteries in place they look pretty on windowsills.Hi I love the candles. They are beautiful and the flickering is so natural and realistic. Nine out of the 10 work and no matter what I do with the remote or physically taking the candle apart I cannot get it to turn on for anything. Can I send one candle back and get a replacement?Very happy with these. They have a real wax outer finish and the timer is great. Best part is that once the timer is set, they automatically turn on again at the same time each day. Remote is handy so you don’t have to mess with window treatments to turn on or off. I had one issue and the seller/manufacturer responded to email in less than a day and quickly resolved it.
