Great price

Lightweight and small. Bought to take with me while traveling as I don’t trust all hotels when it comes to carbon monoxide leaks.

for home, for travel, for car (add to winter car bag in case stuck in blizzard). 9 volt included

I purchased two packs of the pack of 2. So far so good!? Tested fine. Hope it actually works, which is why I went with a name brand. This is not the place to skimp.The C0400 carbon monoxide detector comes with a 9 volt battery. I knew I needed to replace my existing detector (they dont last forever, and need to be replaced ever so often) and I did not want the plug in style. I wanted battery operated so I could place it wherever I wanted and not be limited to available outlets. I also bought a second pack as a gift. I prefer giving practical, functional gifts, especially stuff that people tend to not want to buy, such as smoke alarms, fire extinguishers, carbon monoxide detectors.If you travel, consider a battery operated detector such as this. Dont trust that a hotel room has you covered, or someone else's house. It is small and light weight enough that it should be the thing to pack (take out battery, store separately until in room).I will likely buy an additional pack. Right now I have one on the first floor, and one outside my second floor bedroom door. I think having one in the basement and another in actual bedroom or elsewhere (spread out) would be better. Watch for sales, but if need be just buy them at any cost so you have them.I am even thinking about adding one to my winter car kit. If ever stuck in a blizzard and had to stay in my car for any length of time, having a detector will help as CO2 levels can quickly rise if running car (or if a few people are simply breathing without the window open a crack) to keep warm. Tail pipes can easily clog especially if windy. So yeh, simple thing to stay safe and alive

Vary reliable

My old alarm stopped working and I needed one ASAP. This arrived at my house earlier than expected and was easy to set up. It gives a paper full of instructions in case an actual carbon monoxide leakage were to happen and other helpful tips.

Great item

Good working item

Everyone should have one

This monitor is easy to use and accurate. The battery feature vs plug in makes it easier to place higher up which is better. I always get these for housewarming gifts. One of these may have saved my life in an apartment I used to live in.

Excellent and easy to install

I purchased this alarm to install in the upstairs hallway between bedrooms. It was very easy to install and works perfectly and provides the added security I required. I was surprised and happy at how quickly the parcel arrived!

Simple

Straight forward, and easy to install. Affordable too, everyone should have one.

Safety

This unit is very similar to the one we had for over 15 years. CO2 is a danger & we now feel safe again with the new alarm in place. The unit is just a simple plug in, but we did have to read up on where to put it. Placing it correctly is important so study up & get it right.

Seems good

Quickly mounted to the wall and put batteries in. Tested. Made beep noises that split eardrums. Due to the battery nature of it it can mount anywhere close to the ground to detect CO quickly.I wont truly know if it works, and I hope I never need to, but appears solid.
