I thought I smelled gas. It works great. For the price is well worth having around the house before you call the fire department. I highly recommend this. Review: Saved Granmmie's life! - I kept smelling gas at my Grandmother's house. I could smell it but Grammie couldnt. I called the gas company because this gas meter kept alarming. The gas company's detector wasn't picking up the gas and the gas technician couldn't smell it either. I kept insisting there was gas. This gas meter helped me convince the gas technician to keep searching for the leak. He finally found it and Grammie's house didnt blow up. Very thankful! ## Features - Quick Detection, Safety First: Guard-101 4 gas monitor multi gas detector is designed for rapid detection of 4 types of gases (H2S, CO, LEL, O2).
