WiFi CO Detector XC0C-iA

Easy to set up and appears to be working well. Quality seems good given the price.

My daughter took it with her when she went a way

Love this alternative instead of mounting on the wall. I can put it down low where it needs to be.

Shipped fast. Seems to be of high quality

Only have a green LED lit up which is perfect for having in my bedroom because it's not super bright. Easy to set up and the alarm is loud.

I ordered these for my gas fireplaces—one upstairs and one downstairs. They plug in and work well.However, they either didn’t come with setup instructions, or I accidentally threw them away when opening the package. Either way, I had to rely on YouTube to figure out how to set them up because just plugging them in caused them to beep loudly and continuously.Once I figured it out, they’ve worked without any issues.

Had to replace an old carbon monoxide monitor. Easy - just plug it in.

We ordered this and then promptly ordered a second to replace CO sensors that had reached their end of life. This one has a slimmer profile, which surprisingly is really important. The older ones were so bulky that any time they were lightly bumped, they'd fall out of the plug - many times happening when we didn't notice until it beeped loudly at us. These stay securely in the plugs.They're also easy to read/decipher. Our last ones had one single red light that would flash different patterns, and you had to know what pattern meant what because the alarm and low battery sounded the same. This one gives a different light, had it written on the front what each light means, and it tells you the PPM of CO.It's hard to truly test it, since we don't have CO for it to register, but it appears to work well.
