This monitor works well. It starts up in about 12 seconds and updates its readings every 5 seconds. Accuracy seems good, indicating 412 ppm outdoors and reacting appropriately when indoor ventilation is changed, so calibration is likely unnecessary. The screen and indicators are clear, with a nice chart that you can change to monitor different things over different time periods. However, the display has limited viewing angles - 30 degrees above straight on is best. The only features that I am missing is a way to turn on the backlight and a way to suppress the alarm for a few minutes. Once you figure out the menu system, there's enough settings to get the functionality that you want. You can switch between different plants or a separate "human mode" for people like me that use it as a personal air quality monitor. There are no "bonus" settings, just enough to handle common use cases. So you can calibrate the sensor to outdoor CO2 levels and set an altitude offset, but there are no options to customize the alarm or target thresholds. The monitor comes with a nice kit of accessories such as two charging cables of different lengths, a power adapter, and multiple ways of hanging it, wall mounting it, or propping it up on a table. You can use the long cable and adapter to power it from the wall, or a battery bank attached with the included Velcro and short cable to make it battery powered. Read full review

Glad I found this CO2 sensor. I have looked for an economical CO2 sensor for years, and this met my personal needs for checking the "stuffy" air in the house since we improved existing insulation and caulked for air leaks last winter. Our house measurements were over the comfort levels, and we used the detector to work out an air exchange plan .. and the air in the house is noticeably better. I'll be visiting family in the next weeks, and taking the CO2 monitor with me to possibly see why they've occasionally had headaches and feel drowsy more often than not when they are inside. Good features: Quick measurements, easily adjustable for plants or people settings. Easy to read display. An LED light gives "green/good" vs "yellow/marginal" results visible from across the house. Seems to very accurate. Even notices when I walk thru the room with a change in higher CO2 readings. The unit would be even better if it had an internal battery, rechargeable or AA, for quicker room-to-room portability.Read full review

There are no cons. It gives me all the information I need at one glance.

Works well for the terrarium plant project I am doing. The backlite only works when a function is selected. This does not affect what I am doing. I recommend this for in house or small indoor gardening uses.
