poor workmanship, thin cable

The chain's total cheap product (from the Far East, I suppose). You have the balls all press itself only in the form and then put on the lights. The picture with the wrapped around the balls is wrong !! A bit tedious, but it works.
The description does not mention that the cables are plugged in via an adapter (made in China?) Into the socket.
This contributes greatly to the plug (if you have him lie behind a shelf or similar).
At the other end there is a kind of terminal block, which is not nice visually.
The chain can not be made by a switch on and off, but only by removing the plug.
It was not clear when ordering me.
I have therefore bought and installed a safety plug and a switch. But as the existing cables are so thin, they can not slide properly into the terminals. I do not trust the connection and will dispose of the chain.
