The installation and commissioning was done easily and quickly, but the trouble was, unfortunately, nothing! :(
Negative is also the transformer on the plug, the more power is consumed.
I can say from experience, always on the Newton-meters (Nm) specified pay (the more the better) and prefer to buy an oversized unit than to make the effort to install a weak unit.
If you have a very light roller shutter it might work, but I can customize the unit to my experience, unfortunately, do not recommend!
