Does the job just

This programmer works well for several months. I plugged in a heater on and it is good when you get up.
The implementation is very simple:
1) Move the small spikes to decide the hours you want the connected device operates above (a pin is about 10 minutes)
2) Set the black triangle in front of the time it will be when you connect the controller to the mains
3) Push the button on the side to "I" position to activate the program

Only flaws:
- Makes a low DC noise that can interfere with concentration if you are out and about in absolute silence and acute hearing, so to remove or isolate in a box or closet.
- Takes a lot of space on a power strip
- Not suitable if you want a different setting every day
- Obviously, the settings will be moved in case of a power cut.

I hope that this testimony has been helpful, thank you to click "YES" below if this is the case :)
