Good value for what we needed.

The monitor comes with a set of instructions, and a usb-c charging cable. Mine came with a full charge which was nice. Just follow the directions to turn on and it’s off to monitor your air. This is nice information to have especially now that we’re going into the cooler months where the doors and windows will be shut more than they will be opened. It nice that it will display temp and humidity along with the co2 ppm number. It will also display a color coded “smiley face” on top depending on the air quality of the room (green, yellow, red). This will either give you peace of mind that your breathing clean air or are in need of an air purifier.Overall I’d recommend for the price and the valuable information that it provides you and your family with.

This 3-in-1 air monitor does a great job tracking carbon dioxide, temperature, and humidity. It’s small and portable, making it easy to move around the house or even take on trips. The display is clear, and the readings seem accurate, providing peace of mind about air quality. Recommended.

This is a tremendously useful and valuable device. That cannot be overstated. I learned the area I was sleeping in had a very unhealthy level of CO2 during the night..( > 1000ppm) this allowed me to take corrective actions regarding the airflow in my home and cut that measure in half ( ~ 500ppm). The results to my health and well-being have been mind blowing.Now I wake feeling MUCH more refreshed, my energy levels are up, as well as more consistent. The stuffy cold/flu that had been hanging around for OVER 4 weeks disappeared overnight.We all know that we should have fresh air in our homes, but please don't assume you do, or that it is at consistent levels throughout the home (even with AC working) as I did... get this little device and BE ABSOLUTELY CERTAIN of it. The results are worth their weight in gold.NOTE: The CO2 measurement is not instantaneous like the temperature and humidity, rather it gradually adjusts to the environment, so wait a little while for the reading to stabilize before properly taking the reading.

I selected the inexpensive TC-10 model, the round one.While I do not have a way to properly test this unit for accuracy, it delivers sensible CO2 readings for the environments in which I have tested it. Temperature and RH agree with my other known-accurate sensors within a degree and a couple percent.Operation is very easy, one button to power it on/off, and another to set the alarm threshold. The default setting is 1000ppm.The screen is easy to read, although the backlight is a little dim. I imagine this is a compromise for battery life, but I'd honestly prefer one which doesn't need a backlight at all.Regarding that battery life, it's quite good. Using an inline power meter, it fell just below the rated 1500mAh. Even so, it lasts far beyond the rated eight hours on every charge, so I can't really complain. The only issue I have is the charging connector; it's micro USB instead of type-C. Still workable, but I wish I had known beforehand. I'm trying to not admit anything with this old connector into my household, these days.The price on this is right in line with other detectors of this style. Really, the only complaint I have is using micro USB instead of USB-C. Otherwise, it's great.

This air monitor has worked well for us. I have found that it has been very accurate and helpful to know carbon dioxide levels in my brewery. Added bonus is that it gives the temperature too. This is small portable and easy to use and move around to test different areas. Works great so far

I like it, it works very well, but you pretty much need to leave it plugged in it might last two days on a charge.

Instructions are translated. OK but typical Chinese --> English so there are some cryptic lines. Takes a while to figure out. Expensive shop around and decide. Not outrageous difference but enough for me to notice. Very easy to read. Does not have C connector. Battery charger is EU pin style rather than USA, Doesn't hold charge well, , well old style. Only markdowns was price versus features, unusable power pack, short battery life, and no C connector. The actual technology seems fine. The humidity and temp are right on.
