The coffee perfectly fulfills its function programmed for morning coffee, but terribly disturbs the electromagnetic environment of the house, including the FM band, it becomes almost impossible to capture the radio (indoor antenna) without disconnecting the coffee (too bad for FM radio in the meantime, if you must reprogram the coffee, even if it goes fast, it is not practical) and the coffee also disrupts my remote controlled taken pontuels operations, which become unusable because normally I am obliged down the stairs to put the remote control within a meter of the radio-controlled socket of the Laser printer. I tried several channels, it's more or less the same.
