Lifesaving product - buy it!

This GasKnight saved my brother's family. He left the gas stove on and went to bed. The alarm woke his wife up! Great product! Buying one for family members

Peace of Mind

Very simple instructions and easy to install (just plug it in and let it do its thing). I feel better having this extra level of monitoring of our gas appliances.
