Dear Rudi,
From today I am also connected to your wonderful alarm system. Although I have been living in the Netherlands for some time due to Francine's illness, I would love to use Chequi's services now, even during the long walks I do here in the beautiful surroundings. This initiative deserves all the praise and will certainly be useful in emergency situations due to the simplicity of the whole.
Best regards and good luck.
