- Cable for power supply is very short, especially if you want to mount the thing perfectly
- The electric buzz is already borderline for living areas, got it mounted in the kitchen, already interferes with the cooking, I just closed the kitchen door otherwise störts me even in the living room right next to it. Noise Sensitive people please stay away.
I empfehl the gas detector anyway, at the price you get the security of knowing if gas leaks.
