I have tested the lights and even a few hours in operation. All lit up from the beginning. It has gone no fairy lights broken. The warm white light comes across well. It is comfortable and ensures Christmas spirit. The cable is transparent, and not in a gaudy color. So it falls to less.
The small switch can turn on or off the light easily. The batteries could be easy to place them into its compartment.
The processing of these favorable light string is ok. Of course you can not compare with a 20 euro Lichterkette it. You get a decent goods at a very good price-performance ratio. Commercially I have seen equivalent mini lights that were much more expensive.
By the way, these mini lights fold super small, one hardly loses place when you wegpackt until next Christmas somewhere.
Do not regret the purchase. I would use any time again.
