Pros and cons

According to our carbon monoxide detector expert

This carbon monoxide detector detects odorless and flavorless carbon monoxide gas.
The detector runs on batteries, so it's wireless and can be placed anywhere.
You can use this detector for a very long time, because it has a lifespan of 10 years.
You can't wirelessly connect this carbon monoxide detector to other detectors.

Description

The Alecto COA3910 carbon monoxide detector warns you if there's a risk of carbon monoxide poisoning. The sensor of this detector lasts 10 years. That means you can be sure you'll get a notification in case of too high or too low carbon monoxide levels for the next 10 years. The detector gives you a quick insight via the display. It also does so when the batteries are almost empty, or the 10-year lifespan is almost over. Via the display, you can see the exact level of carbon monoxide and the status of the battery. You can easily place this detector with the included base plate, screws, and plugs. This detector doesn't stand out, thanks to the coarse texture. This makes it look like a plastered wall.

fine

Good information provided
Simple device, no frills.
No information when the 10 year lifespan ends.

Simple thing that seems good but lacks all quality documentation. Very good at informing which levels are threatening and dangerous. If the negatives are taken care of, something like this should be in every house. More important than soot or smoke detectors.

A necessary device.

Does what it is intended for, measuring carbon monoxide.
Flashing lights a bit annoying.

I think I need this device, but because of the flashes of light it can't really stand in a bedroom, so it's in the attic.
