Bought there ten days, used 2 times, I find myself today with an empty gas tank, and the obligation to buy a new (or pay 20 euros for a refill ...) why ? Blame the presence detector is defective in any obvious: when it snaps once because it has detected a presence, it can not stop ... so if at that time you are in another room of the house, impossible to hear that he is being emptied completely. Disappointed :(
