Device works really good for the price. I charge barely once a month and works through the month.Based on my living condition, its so accurate on co2 level and I know when to open the doors and windows and make fresh air enter inside the house.One con is that alert tone is very mild, like similar to wrist watch beeps. So almost all of the time, you cannot hear it.

Worls perfect for my needs. I liked it so well, I bought a second one. If you buy one, recalabrate it, Easy to do.If you are growing in a tent? You will need 2, (inside/outside) this way what is going on. I do like this CO2 meter and I will be buying another one soon.

Something I bought that I badly needed for my detached CNC room. At times a lot of smoke is coming off my laser. Not only does it show the current CO2 level, it also shows the temperature of the CNC room. I can use my laser when it’s in the 40’s outside with my exhaust fan running for two hour bursts. Now, before I open the door. I can make sure all the CO2 fumes are flushed out. The CO2/Thermometer has a Bluetooth function. So I can monitor everything on my iPhone.I sit back in my bedroom and watch my CNC from a Geeni web camera. Now, I can wait until the CO2 level drops before I go back in the CNC room.To my surprise, the CO2 level actually dropped when I started using my laser with the exhaust fan running. My only concerns about the CO2 meter is that the screen is very faint. But I can view the levels on my iPhone.The CO2 meter does work well. I breathed on it for a minute or so. It showed the CO2 levels went up to a dangerous level.Setup: The instruction manual advised the app would connect Bluetooth to the CO2 meter. That did not work. However, I manually added the CO2 meter to the app using the QR code on the back of the CO2 meter. I set the time using the app, and many other functions.

Calibrating took some trial and error.I'd suggest you calibrate the unit by first taking it outside let it acclimate to the outside air for 15 minutes, then calibrate. Once done, bring it back inside. You may notice the numbers jumping around a lot. Just let it do its thing to adjust to inside air and temp. It will eventually settle down.

It arrived packaged well and had the appearance of NOT being some cheap thing that would break soon. It was fully charged or appeared to be. The instructions are tiny but the first page has a QR code that I scanned and it pulled up the instructions on my phone. The information was helpful and I was outside calibrating it in just a few minutes. Calibration is done outside, away from pets and people and it takes 200 seconds. It also has a nice little stand with a metal bar on the top that the monitor latches when it is set on the stand and it sets up nicely and is easy to read. The monitor having a magnetic back can also be attached to a metal surface like a refrigerator for instance. In conclusion I run a propane heater at my fireplace in the winter and it may run for 12 hours at at a time. I have a few CO and explosive gas detectors throughout the house to alert me of dangerous conditons so that I don't wake up dead one morning from CO poisoning or get blown up from a propane gas explosion. The one thing I didn't know is how much CO2 was building up in the house from being closed up with a propane heater running so long each day. It gives me peace of mind to have the monitor but I really don't know how good it really is because I don't have anything to compare it to and I just started monitoring CO2 with it but I have to believe it will give me good information until I have reason not to.

I purchased this along with a more expensive device to test CO2 levels. Neither device agreed either each other within the stated error range but both are handy at helping you understand how levels accumulate. The device seems to sip energy so a charge lasts about a week or more.

I have the Temtop M2000 hand monitor. I added this model because it has a longer battery life so I can leave it on all night hoping to get alerts if the C02 goes into a red zone. The readings between the 2 monitors differ by over 100 ppm so accuracy is questionable. Also this model doesn't have a backlight so you can't see it during the night unless you turn on a light. At this price point I can deal with not having a light but I'm not sure which of the 2 monitors is most accurate. Customer Service is excellent and responsive but we were not able to solve this problem. Since the monitor hasn't gone into the red zone I can't say whether or not the alert works. I'm keeping it but can't give it 5 stars.UPDATE: I recalibrated both monitors and they are syncing more often now, to within 50 ppm. The long battery life is impressive but this monitor rarely goes over 800 ppm when the handheld monitor is beeping in the red zone at much higher levels. Not sure why this particular monitor doesn't go high enough to hit the buzzer. Since the handheld was tested and approved by EPA I trust it more. For the price point this monitor is adequate but if you have issues with high C02 levels I recommend getting the Temtop handheld.

This was tested against a very expensive co2 meter that I borrowed from a friend who works in confined spaces. It was very close there was 18 point difference. This was very affordable. The read out is not very high in contrast but it is readable. The temp and humidity levels appear to be accurate as well tested side by side my analog wall meter which I usually tap on. There is no backlight on this. The readout is equal to a large calculator. I am very happy with this purchase especially for what it cost. It is rechargeable so I don't have to purchase additional batteries.

This is a very useful device which measures Co2 in the air (and also humidity and temperature). It is fairly simple and seems roughly accurate. I give it only four stars because the setup instructions are not clear and the product support is fairly poor (automated "answers" which give generic statements that don't answer simple questions). This is a common problem with electronic products but that doesn't make it OK. It should have been super-simple to set this up but instead I had to go around and around on Amazon, looking for answers to simple questions, eg, How long does it take to charge initially? Is it necessary to calibrate it outside? (instructions are given on how to calibrate it outside, but it doesn't say whether this is necessary, or why).
