Low Level CO Monitor | WiFi Remote Detection

This gives me such a huge sense of comfort. Shortly after this arrived, my neighbor had a house fire. After standing outside around smoke for a while, I thought maybe I needed to be concerned some CO ended up in the house through door cracks. I was able to check this monitor and see my pets were completely safe by seeing a 0 on the monitor. I cannot begin to explain how grateful I am for this product. There also was a hiccup with USPS losing the first package, so Forensics Detectors sent a second one immediately. I highly recommend this product and company.
