X-Sense Carbon Monoxide Detector, Replaceable Battery Powered CO Alarm with Digital Display, Portable Carbon Monoxide Detector for Travel, XC0C-SR, 1-Pack

Bought this Carbon Monoxide detector after hearing on the news about people passing away in Mexico while on vacation due to Carbon Monoxide poisoning. Then hearing experts recommend to always travel with one because it's a silent Killer, you cannot see, taste or smell it. Things I like about this device: 1. It "solely" operates on batteries (Only have to worry about having working batteries and don't have to worry about a power outage) 2. The display shows the battery power level ( So I'll never have to wonder if I have enough battery power). 3. The screen displays the carbon monoxide level. 4. The display light doesn't stay on. A button is on the top that you can press to read the screen when you're in low light. 5. The front of the detector indicates what the different color lights mean, so anyone can easily know what's going on. (Green-power) (Red-Alarm) (Yellow- Fault). 6. It is LOUD. Ear piercing loud. Cannot imagine a heavy sleeper sleeping through the noise it made when I ran the test. 7. Compact, flat on both sides. (It was heavier than I expected it to be when I first held it, since it says perfect for travel (weight is probably because of the batteries). Either way, I've never held one before so I have no source of reference to compare it to, but I'm glad I have this to travel with now. No longer have to worry If the place I will be staying when I travel has one). WHAT I'VE LEARNED: Instructions were informative and helpful. Gave tips on the best places to install it. It also reiterate that this device needs to be replaced in 10 years. The device will tell you. While reading the manual, it gave time frames of when an alarm would sound. After doing a google search, I discovered that Carbon monoxide detectors do not sound immediately after detecting the gas. Rather, it sounds within a given time frame based on the level detected. Further reading on Carbon monoxide shows that the time frames listed in the manual of this device is in line with what's expected from a Carbon Monoxide detector. These are the levels posted in the manual (I also posted a screenshot of the manual) 70 ppm for 60-240 minutes, 150 ppm for 10-50 minutes, and 400 ppm for 4-15 minutes. I have no dislikes yet. My hope is that it works when it's supposed to. I currently have it mounted with double sided tape by the door in my bedroom, so I can pop it off when I'm taking my next trip. Hope this was helpful to someone.

This little detector packs a lot of safety into a compact unit. The peak value memory is super handy you can see if there were elevated CO levels while you were away. The alarm went off during a test and it was very loud and noticeable. Peace of mind for such a low price!

Seems very nice. Small, easy to place and read. I assume it's working properly, but won't actually know for certain unless I have a carbon monoxide leak, right? Meanwhile, it seems to be a nice piece of equipment and the price was certainly right. I actually bought extras for gifts.

I purchased this carbon monoxide detector for added safety in our home, and I couldn’t be happier with the decision. Setup was incredibly simple—it was up and running within minutes right out of the box. The instructions were clear, and it came with the necessary mounting hardware, which was a bonus. One of the features I really appreciate is the loud, distinct alarm that’s impossible to miss. I tested it using the built-in test button, and the alert was strong and reassuring. It also has a clear digital display that shows real-time CO levels, which gives me extra confidence that it’s actively monitoring our air. Highly recommend this detector for anyone looking to upgrade their home safety system. It’s reliable, easy to use, and worth every penny!

One of my wife’s biggest worries has always been carbon monoxide, especially when we’re staying somewhere unfamiliar. I picked this up mainly to give her peace of mind, and it’s already worth it for that alone. It’s compact, lightweight, and easy to pack, which makes it perfect for travel. Obviously, I hope I never have to find out firsthand how well it works, but based on the build quality and how reliable it feels, I don’t have any doubts about its accuracy. The size is just right—not bulky, but still solid enough that you feel like you’ve got real protection with you. For something so small, it brings a huge sense of security. Now whenever we’re away from home, we can relax and not have that “what if” in the back of our minds. Definitely a worthwhile purchase if you want some extra reassurance.

Easy to set up

This works well and is a nice portable CO detector that you can take any where. The alarm is so loud ....no one is going to sleep through it.

Seems to be working as it should. We used it for camping in a hot tent for 5 nights with a kerosene heater and it never went off and we are still breathing.
