Pretty accurate sensor, extremely comparable to my others that I use. I really enjoy having one of these because it really allows me to dial in my environment exactly how I like it.

Good value and this one works properly. The first one had a faulty charging port but this one works well. Do wish it would run longer on the battery. I just keep it plugged in as they recommend which makes me wonder why they put a battery in it to begin with.

Works as advertised. The battery life is pretty good. I leave it plugged in most of the time but I like that I can unplug it and move it to another room to get an idea the CO2 levels

I tried it out for a while and wow it is really accurate I like to keep it by the center of my room since I need my temp and humidity on point most of the time. The carbon dioxide detector is great because my room doesn't have one so keeping one of these on at all times is especially safe and the long charging cable is the best lets me charge it without moving it.

I like the ease of how to set up and read the tempter and humite along with the CO2 readout. I have a old heater in my house and want to keep a eye on the CO2 it puts out as it runes. Would recommend this to my friends and family.

I like the ease of set up and calibration with this meter. Set up was done in my dining room with two adults and gave a reading of 114 ppm. I placed the meter in my grow tent and have gotten consistent reading of 408-412 ppm. Temp and relative humidity have been very close to analog Temp/RH meter in tent. This item performs as expected and I will be using one in all growing areas.

The display is really clear and easy to read, One of the best instruments displays I have used in a while, even better than expensive medical instruments used in hospitals. The temperature and humidity measurements are more accurate than my nest thermostat. The CO2 reading is good enough for the purpose (I did not have to calibrate as it was already giving me accurate reading (410 ppm) outdoors. When I have all the doors and windows closed in my home. and running the AC. The CO2 levels rises to around 500-600 PPM overnight. When I cook things on the gas burner and have the windows closed it further goes up to 650-700 ppm. When I leave the windows opened and turn on the roof ventilation. The CO2 never goes up more than 450 PPM. During Covid its really important to have the CO2 less than 800 PPM this instruments helps me undesrtand the importance of ventilation in helping reduce Covid spread.

Very accurate and reliable. It's got some weight and feels like an actual tool not a junk box. Battery life could be better but I mean who is gonna use it unplugged for no get than a day or two?
