Multiple has already referred to the professionalism of this system, I can confirm - it's not cheap, but also not as it looks. Do you have to buy each extension a starter pack, then it's expensive - but the system is probably not intended. You should already have multiple extensions per starter. For durability: use the system for some years and had only one failure, one of the first chains gave up after 3 years, the other from the first series to do well this year continue your service. For color: The Cool White here is his name 100% accessible, a little more and it would be blue. Ice white, one could describe it. Among the white varieties: best convince these when mixed - yields a virtual glitter effect, when the wind, the light spots moved - as the night sky as the stars shine so well in different shades of white. For the other colors: it is incomprehensible that there are Amber and Blue, but in Anglican space traditional colors red and green not. LEDs in these colors are probably commonplace. That it would be possible to prove the colorful chains, which I find mixed with this cool white chain very nice. Here no rating withdrawal due to lack of colors, for who is looking whites, probably not miss the lack of color - although, green and white would be interesting as synonymous with a fir with white candles.
