We use the machine every day, however, depending on where we are, the range could be a little further. Even with the deployed antenna the range is just as adequate for our apartment, where there are thick walls makes the device well before at about 10m through walls and doors limp. The tune function can be forgotten in any case, that does not help to terrrorisieren to fall asleep but the child with loud Gepiepe ;-) All other operations are top!
