First of all the detector is really small and fits to the windows in a perfect way.
I have used the small magnetic ring, which you can see on the 2nd product picture (upper left).
I had an issue to find the right position and the MySupport from Credex just helped me very fast.
The magnetic ring has to be positioned close to the red light!
And wow it fits and works well now.
Definitely a great product and a great support!
The magnet contacts are really nice and small. Even for windows without much space between the frame and the wall, they nicely fit.
For normal houses the coverage is enough.
They fit seamlessly into the system.

Nice design, small footprint. A must for every door. Im adding a dedicated indicator element at the access panel showing if any of the doors in the house are open.
