Review on CC091 Gas Leak Detector: Propane, Methane & Natural Gas Sniffer with Gooseneck Sensor - Adjustable Sensitivity for 50-10,000 ppm - Audible & Visible Alarm by Shawn Sims

Every home should have this. This is a natural gas detector that can save lives. On the top is this antenna-like thing that fits in places you normally can't get to, and on the top is a sensor that detects gas. It's easy to use, seems accurate, and affordable. It detects all types of gases, not just one, but all of them, which is a plus. This one machine is all you need.
