Really good CO detector, battery lasts over a week per charge. Alarm sounds loud and clear when tested. Clip fits secure on work belt or pocket. Used it near boiler recently, picked up small leak straight away. Red light flashes bright if levels go up. Vibrates strong enough to notice through thick clothes. Survived accidental drop from ladder. Readings match the expensive council detector. Comes with USB charger cable. Very pleased. Would certainly recommend. ⭐⭐⭐⭐⭐

If you're looking for a reliable and portable carbon monoxide detector, I highly recommend the Guard-566 Portable Carbon Monoxide Detector. This device is compact and convenient, offering peace of mind whether you're at home, at work, or on the go.One of its standout features is the rechargeable battery, which provides a long standby time of 168 hours – that's over a week of constant monitoring before needing a recharge! The back clip makes it easy to carry around, so you can even attach it to your bag or clothing for portable use, and it’s great for people who want to keep track of CO levels in multiple environments.The vibration, visual, and audible alarms are incredibly effective at alerting you when carbon monoxide levels become dangerous. The adjustable alarm thresholds are also a great feature, allowing you to set it to your desired sensitivity based on the environment.This CO detector is perfect for use at home, in the workplace, or even when traveling. It's easy to use, and the multiple alert systems ensure you’ll never miss a warning. Whether you need a detector for safety or just want an extra layer of security, the Guard-566 is a solid choice.

A well-made device that comes in a strong case that will hold additional accessories. It's extremely simple to use. I read the instructions but everything is very intuitive as it only tests for one compound. I love that it has an internal rechargeable battery and that the display shows the battery's state of charge. I've run the device for 6-8 hours so far and the battery level is still at maximum. The display is good quality with clear text and a backlight that can be toggled off or on. It's small and light (comparable to a small smartphone) and has a good clip for attaching to the exterior of clothing or gear.I first tried testing it in my apartment and it wouldn't show anything above 0 ppm, which is great. I figured it should detect some CO in my building's parking garage and it did. It ranged from 0-6 ppm in the garage. Also, when I start up my old car and turn the cabin heating on, it sometimes gives off a gassy smell for a couple minutes. So I tested it in the car after it had been off for a long time and the engine and catalytic converter were cold. The device showed that CO levels briefly peaked at 17 ppm before dropping back down to 0. The readings update every few seconds.So overall it seems like a well-made and reliable device that's also easy to take with you into situations where you may be exposed to CO. It could also be used as a home CO detector although you'd have to remember to charge it regularly (perhaps weekly) or leave it plugged in.

It's simply not acceptable to still be making devices that use mini-USB in this day and age. That adds a completely unnecessary, single use cable to my tech pouch and who wants that? So many people don't want that that the EU banned it across a broad range of portable electronics. This should charge via USB C.It comes in a massive case which is far larger than you need to hold this, the cable, manual and one plastic clip. That's an odd choice as I can see why you'd want to protect such an expensive piece of kit but it's hardly delicate and surely doesn't need to have so much foam and bulk to do that. It's basically a marketing point that you get this box not a practical issue and I'm pretty sure most people will repurpose it or throw it away. Hardly environmentally friendly, nor is it rational since they could have supplied an appropriate sized box just as easily and saved packaging of all types.The device works well though and is easy to operate with simple functions and audio options depending on how you want to be alerted to the presence of carbon monoxide. If you are a professional, or have a suspicion you have problems in the household, this is well worth it. Note that this is for spot testing. It's not a static alarm to detect harmful gases in the household so isn't appropriate for that.Also, just in case, lets be clear and say this detects carbon monoxide which is odourless and lethal, it doesn't also detect CO2, or smoke or any other gas or air quality. It's more useful for people in a trade that are looking for problems, than for householders who should get a general smoke detector or a carbon monoxide detector particularly if you have wood fires and the like. This is only on when you turn it on, it's not for monitoring anything long term.
