The perfect Christmas tree lighting

After much pros and cons of the battery LED lights has been written with respect, I want to do at this point my own experience known:
- We had the lights on every day about 2-4 hours, the batteries that came gave until after Christmas, ie approximately after 3 weeks, her mind on. Perhaps some buyers have caught on stock? I had added myself definitely enough spare batteries that I have nevertheless not required!
- Unfortunately, I could see a warning of any single, which indicated that the battery is empty soon
- We have made the switch because the lights are to be placed by the children very easily in the tree. With normal light strings, there is usually a shambles.
- The remote control works reliably, if you do not just 1m stands in front of the tree. From 2-3m distance get all the candles, and turn on the on the backside of the tree, a clear signal to.
- The brightness is fully sufficient that it gives an atmospheric light. You can look at the tree, without thereafter minutes to see white spots.

Of course it is ecological nonsense to put lights with batteries to the tree, as the conventional lights have an advantage. But it's not just not ecological to transport a tree for hundreds of kilometers, so that it then dries up in the living room?

I can only recommend the lights!
