### ⭐⭐⭐⭐⭐ Accurate and reliable

Easy to use and perfect for safety on the job

### ⭐⭐⭐⭐⭐ 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.
