Easy to Install

This item arrived very quickly. We were surprised at the ease of installation. The alarms on it are great - veryloud, very informative. it is small and unobtrusive, and gives us a sense of security with our gas stove.

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.
