We have admittedly rather large Christmas trees for years and have in addition to real candles for 'fast times' also electric on the tree. However, the existing chain was a 'normal', which means that all lamps sitting in a row on the cable and the plug at the end of the whole thing combined into a large circle together. This circle is - especially for large trees - but usually very difficult to 'relocate', because you must first with the middle of the cable over the tree top. In addition, the distances between the candles are usually quite short, so that the 'jump' from one branch to another is difficult itself and leads to crooked candles. In this chain now that everything is much better. The distances have very auskömmliche 70cm (!) From candle to candle, so you can position this really where you want to. And the 'One String' in the article means that two wires from candle to candle and run the plug so just sits at one end of the strand. So you can easily start near the power outlet and then work up the tree - until the chain to the end and the tip (hopefully) has been reached. Now that is handy!
Quasi by the way - the candles are elegant, unfussy, the light very pleasant and subdued, even harmonizes perfectly with real candles (as we have tried from time to time).
All in all, a full recommendation - that thing is really worth the money!
