Small but effective and a great price. We use them to monitor gases in high risk areas on our farm (shop/animal housing/waste lagoon area).

Update- seller did the right thing with quick followup and resolution.Ive been a firefighter and Haz-Mat Tech for 40 years. I purchased 3 of the Natural Gas Detectors and have had them in use for7 months. Seemed like a good purchase with decent reviews, however I have experienced a disappointing slow response when I tested with natural gas from my cooktop. I have also had numerous false alarms while cooking. The detector is 20" to the side of my gas range cooktop. I have an over-the-range vent that exhausts out of the house. I also installed one in my mothers kitchen and the third in my In-laws kitchen with the same issues. I suppose it could be a bad batch. At this point so unreliable we have decided not to use them. 'UPDATE: The manufacturer reached out to help resolve the problems and I appreciate the effort. I will update again after resolution.
