Review: Accurate, great safety product, recommended for heaters for in enclosures - Seems pretty accurate always nice to have when you’re using the propane heater in a tent or enclosed space being able to tell your oxygen levels and carbon monoxide gives you a little bit more of reassurance that you’re not gonna just wake up dead
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!

### ⭐⭐⭐⭐⭐ Low cost monitor but actually not too bad
*by S***O on September 23, 2025*

Part of my job is training new individuals for confined space. New individuals are often unsure of what they are doing. I wanted an air monitor that would work but also be expendible if the trainee would drop it or it would get misplaced in traveling to and from locations. I compared this unit to my name brand ones costing 5 to 10 times more expensive. Its actually significantly more accurate than i would have expected. I would actually reccomend this unit. Its a great value for a first air monitor. It was very easy to used and battery last forever.
