These lights here are cheap and excellent!
I own both the chains in cool white and warm white in the.
Both have their advantages. I use cool white and warm white love for the outside I prefer indoor because it feels comforting.
The lights are designed so that you can expand to other chains. As mentioned in another review you can here but let the assembled chains run in different modes (for example, let a continuous light and leave the other flashing).
Which brings me to my next point already.
You can via the control unit 8 different modes in your region everything from lit steadily leave to flash (the detailed description can be found on the product page).
I prefer to use the Sequential setting- but that's a matter of taste. My wife has it like when the lights throughout the luminaire thus is with us, the mode is run.
At the processing is like saying nothing to complain about and the service life should be longer than with conventional lights.
