Search for a long time I have decided to use this product. Delivery was on time. The candles made a good first impression. Although the onset of the batteries was some work, but worked flawlessly. Turn also the first time worked great, all the candles have burned. The installation on the tree was relatively easy (of course compared to tangling with the previously used candles) - that was also the point of it !! Of course, the candles are a bit heavier and therefore can not be applied to very thin branches - but it is also clear, and thus no problem. Even with the light of candles turned on we were very pleased. There are continuous light and flickering 2 stages. In use was always the lighter flicker level. The strong flicker was too restless. But the slight flickering really liked us and also all Christmas guests, it has a pleasant, warm candle feeling. Now the life of the batteries: superior After prolonged but I used the supplied batteries. Switched on, the candles were about 7 hours a day, almost every day from December 24 to 12.Jänner. In sum, I had the last few days at 5 - 6 candles replace the batteries, all the others have persevered. I had not really expected and am amazed at how long will the batteries. All in all, I did not really expect such a great product and I am therefore very pleased with the price / performance ratio. I would recommend this product only !!
