Great product for peace of mind!

These are great for everyone that uses Natural Gas. These are well built, and easy to install. Definitely recommend to anyone wanting peace of mind, knowing that you will be alerted to any gas leak and can take action before a disaster would strike. We placed these next to our CO2 detectors and now we know we are covered. Thanks Marc, and the DeNova Detect team for making a great product!

Easy to understand, easy to mount. We installed them adjacent to our three CO detectors.
