not huge on the noises it makes but great for determining air quality when traveling.

I love this CO2 monitor, because it's easy to clip on to my purse or backpack and gives accurate easy to see readings. I have seen it go up and down as a enter a closed car and then let outside air in. The color system is helpful for beginners to understand risk. I have seen it go up to 5,000 ppm at a place! I'm so glad I can see the CO2 levels anywhere I go now. Excellent product for anyone trying to monitor air quality or reduce airborne infections. I ordered this a year ago and its still going strong!

The alarm can be turned off so that’s good! This came with good instructions. Size is reasonable. It seems to work- calibrated it outside. Inside my condo it’s reading 1100ppm. My work place which ramped up fresh air % intake on our hvac system (and wind tunnel flow rate) is reading 750! I only charged it once but it charged fine. Screen is easy to read. Recommend! Edit to add I’ve had this 2 months and it’s still going strong. V. helpful in places like airports to understand where there’s fresher air ..and where it’s not!

Pretty useless because battery only lasts a day after fully charged for hours. So if you plan to use it as a mobile one, please consider other products. The only way to use it is to always keep it in the wiring.

I wanted to believe the iffy reviews were flukes, but this isn't a perfect cheap device. It's a bit buggy.I have an Aranet and just wanted a cheap/easy way to check spaces I'm in throughout the day without bringing that everywhere as it's expensive. I already know what my house is like and how my office is ventilated after using that for a while. Compared to the Aranet, the accuracy is close. As others have noted, it seems to be off on higher readings, but you get the point when it's that high anyway. Arguably, accuracy is a huge point in its favor.So it has worked most of the time; I know that my car gets bad if I recirculate the air, the title bureau office where I do a lot of work errands is well ventilated, etc. The problem is mostly in its reliability & bugginess.Edit: I found a manual online (no idea where I put the actual copy) that says you have to use the USB-C cord it comes with to charge it. No idea which cord that is now, in my drawer of cords. Completely defeats the purpose of using a universal port like USB-C in the first place. Can’t charge it at work unless I bring the cord with me, can’t consolidate cords for travel, etc. I’ve been charging it overnight with an cord already plugged in at my countertop, so apparently it miiiiight work with other cords, but it’s a gamble? Very annoying. Might as well have a proprietary charger.[Original: There's no indication when it's charging or fully charged. It seems you can only charge it when the device is off? which is fine, but you have to turn it on to find out what the battery status is. The battery lasts maybe 2-3 days for me depending on how much I check readings. That's actually great, imo. Charging can take a while, though. I'm still not entirely sure what tricks work best; it didn't seem to charge when I had it hooked up to my portable charger at work but charged fine overnight at a wall charger.]My main issue is that sometimes, even when fully charged, it reads 400ppm no matter what. If I restart it, that usually fixes the issue, but it's iffy. I'm hoping recalibrating might resolve that if it persists, but we'll see. I confess I have no idea where I saved the manual and I haven't checked there to see if the 400ppm reading is indicative of something specific.Otherwise, sometimes you can hold the button for quite a while before it actually responds by turning on or off. Double pressing the button always seems to work for the sound right away, though.Overall, it does what I bought it for most of the time, but I don't have a lot of faith in its longevity. I don't regret purchasing yet, but I'll update this review if needed.

I got this a couple days ago and set it up - it seemed like it worked reasonably well. The process for calibrating it is not intuitive, but the instructions walk you through it well enough. It did give readings of some sort (I can't back how accurate they were), but the battery life was awful - barely half an hour of usage before it ran ran down and needed recharging; the screen is also only visible from certain angles, and sitting on my desk is not one of them. Last night I tried to get a reading and it didn't respond; assuming the battery had died, I left it plugged in last night (with the USB cable it came with), and it's still fully dead and nonresponsive.I saw a few reviews with similar experiences of the unit dying, and figured it was sufficiently less expensive that it was worth a shot - now I wish I'd just gone with one of the better ones off the bat; the return process is requiring it to be sent back, so now I have to deal with finding a time to drive somewhere to drop it off. Even it it was still working, I would absolutely NOT buy this again.

Primarily used for monitoring ventilation and CO2 levels in small interview rooms. The unit performs well and is easy to carry in a bag or purse. The detector quality is high, so the accuracy is good. You must pay attention to calibration, manual gives the best results, and also battery charge as it is qute small. A portable cellphone powerbank would make a good backup for the device (and your cellphone).

Overall I liked the thing, but it stopped charging within 24 hours of owning it. Tried different cables and chargers; nothing. It did charge the very first time I plugged it in though, so it's a bit strangeWhen connecting it to the PC to see if it registers as a USB device, it does not. There doesn't seem to be anyway to actually log data as a result, so you'll need to spend more for that I guess. :(Another odd issue is that the calibration instructions didn't seem to work. I could get thru half of the process, but it never actually would do its countdown calibration step.. just stuck at "400".Meter responds to CO2 within 5 to 10 seconds, but could take a minute to full acclimate. Seemed reasonably accurate and the battery life can last you thru the day.I bought some other cheap CO2 meter previous to this one, and it turned out to be fake; wasn't measuring CO2 at least, but something else. About the same quality, but at least this one seems real. Not sure there is a cheaper CO2 meter out there?The screen looked a bit "cracked" when I first got it, as there was a lot of light bleed between the LCD character elements on screen, but that went away after some time. Perhaps an issue with shipping or the cold weather or some internal calibration? Not sure, but it scared me at first.[update on charging issue]I don't know what happened, but I resorted to some physical love to try to get it to charge. I "pressed" down on the device, near the charging port area where I suspect the battery is, and it start charging. If the issue keeps happening, I may need to open up the device and see what's going on.For the price, it's okay, though the quality issues I faced leave some room for needed improvement.

Easy to calibrate (for best results, calibrate outdoors, away from cars and people, and turn off before charging.) there are more expensive CO2 monitors, but for my purposes (is this place well ventilated, or not?) this is perfect, and at a perfect price! I have seen side by side comparisons to the more expensive, well known monitor, and they are consistently very close (10% difference, or less.) PLUS: this has a carabiner to clip it anywhere you like. Very sturdy, well made product. Recommend!

I did a lot of 'research' before buying this monitor (eg, reading expert reviews), and it lived up to all my expectations. This is a very simple device - no connectivity, reporting, or continuous monitoring capabilities. But if simple and portable is what you want, this is fantastic value.It is really good a taking a reading even when it's clipped to the inside of my tote bag. I usually have it clipped to the handle and then hanging down inside my bag, so I can discretely check the readout.The set-up, calibration, and operating instructions are very straightforward and quick. It has an optional alarm indicator for high CO2 levels.Pros: small (fits in a pocket or palm; about 2/3 the size of a deck of cards), nice clean design, caribiner clip, display is easy to read (large, bright text and not too much info), super easy to set-up and use (one simple button), quick to charge (requires USB-C), and affordable.Cons: it seems unfair to list these as 'cons' because these are not features or manufacturer claims about the device. But, compared to other types of CO2 monitors, the battery only lasts around 9 hours, there is no ability to track the device's output (you have to view the screen in real-time; you cannot view output that it previously recorded, and you cannot view output remotely); and it may not be quite as accurate as the expensive brands.I scored the device as 5/5 on battery life because it lives up to its claims about battery life.I really like having it when I leave the house, so I can make informed decisions about whether to take my mask off for a quick snack, or whether I need to leave the space because the CO2 is too high.Highly recommend.

Great alternative to the Aranet 4. Probably the cheapest NDIR CO2 sensor you can easily buy.PROS:- Very accurate (I compared to Sensirion SCD30)- Small and light with a carabiner- Cheap- Uses a proper NDIR sensor- Fairly easy to calibrate (read the manual for the button presses)- updates every 2 seconds. (I believe aranet 4 is once a minute)CONS- Display turns off after 1 min (though you can turn it on again with a quick press)- battery life is fairly short ~7-8 hours (all co2 sensors take a few mins to warm up, so it's best to leave it running most of the time)- display is hard to read outdoors- alarm threshold not adjustable, though you can turn it off- no phone app for graphs

A handy gadget that appears to be accurate although I have nothing to compare it to. It worked fine at first, but after less than 2 months it only works while being plugged in. As soon as I unplug it the screen goes very dim and it reads 5000 even if it was in the green zone just before. When I plug it back in the screen lights up again and after a few seconds shows the correct reading as before. I assume the battery has failed. A longevity of less than 2 months is totally unacceptable and deserves less than 1 star. It also resulted in my returning it to Amazon.
