Carbon Monoxide Detector Plug in Wall, WESHLGD Portable Carbon Monoxide Detector for Travel, 3-in-1 CO Detector for Home and Travel Camping(CO Gas Meter Temperature Humidity Sensor)

The media could not be loaded. I purchased this plug-in carbon monoxide detector for extra safety in our home. Setup was incredibly easy—just plug it into a wall outlet and it’s good to go. The digital display is clear and easy to read, and I love that it continuously monitors levels without needing battery changes.I tested it using the built-in test button, and it worked perfectly. It’s small enough to be discreet but reliable enough to give us peace of mind. We have a bunch scattered all over the house and always bring one with us when traveling as well. Since it plugs in, you do not have to worry about it going off in your suitcase when traveling and can just plug it in when you arrive at your destination.Highly recommend for anyone looking to improve home safety with minimal hassle!

Works great and easy to use. Just plugs into my wall and gives me peace of mind.

I purchased this because I have a gas fired furnace. I was able to plug it in upstairs by the furnace so I can monitor if there was any carbon monoxide leaking. Turns out there was none but I like the fact that this unit display is per per million all the time and will give you an alarm if there is cause. Can also move it around from room to room if you want.

I think this is good. My mom made me get it and I haven't died yet!

Love the fact it digitally shows the temperature as well as the humidity and if there’s any CO. We have a propane fire place that is used to heat our home and wanted a simple way to ensure the safety of our family. Works as described and will purchase this again

These are great and just needs to be plugged into a wall socket. Great option if you don’t want a permanently installed detector. Used one in my travel trailer and much better option than putting holes in my walls to install one.

We purchased this for when we travel and it has been perfect. It is small enough to fit in your bag and gives you the price of mind you need when traveling with kids. We have stayed in many airbnbs that don’t have carbon monoxide alarms and the one that we have in our house is much bigger and more of a hassle to travel with.The only drawback is that the screen puts out a fair amount of light, so it might not be ideal in a bedroom if you are someone who prefers complete darkness in the room when you sleep.

DEADLY!!I got this to plug into hotel rooms my family was staying in after hearing some horrible stories on the news. I should’ve tested it first because it DOES NOT DETECT CO2! The temperate & humidity readings are fine but the CO2 readout remains 0 no matter what. I plugged it into my garage with the car running and all doors shut for 5 minutes and it remained 0.BUYER BEWARE!
