Review on High-Precision Handheld Carbon Monoxide Meter | Portable CO Detector | CO Gas Leak Detector and Monitor Tester (1000ppm) by Tony Korek

I thought I bought the Anpiggy brand even though it was around $56. When I received it, it was the "Smart Sensor" brand. that's $20 cheaper. I mean I get it it's the same product but I thought maybe spend $20 more and maybe get something more accurate and reliable. But I have no idea. That's what I ended up with. Don't order here, just buy a smart sensor and save $20 or pay an extra $50 and get a better one.
