    Seems to work well. The CO2 detector is sensitive. If I breathe on the unit, the numbers will change. I don't know if the reading is properly calibrated though. Don't know what TVOC or the Other Gas readings are, but the temperature and relative humidity readings are correct. The unit does have a battery, but the instructions don't say how long it will run without being plugged in.

    I received the item safely in 21 days, which is absolutely fine, thank you so much. The products was well packed, visually it looks being made of good quality materials. More time is need to determine if the device provides any correct measurements of what it is stated to be capable for, namely: the CO2, ("Other Gases"), Average Air Quality, Temperature and the Humidity in the interior environments. To be able to keep the device constantly on, it needs to be connected to the mains via provided USB cable since the inbuilt battery does not store the energy for very long (about six hours average). The plug is not included in the set, so one needs to have one its own, depending on the region, I have an extra one for the UK/IRE, so I was able to connect the device and to charge it for the first time and it works well. Wishing a very Happy New Year 2021 to Everyone!

    The package arrived destroyed, but the object seems to have withstood the impact. It is now in charge and tomorrow I will try it.

    It seems to work great, but need a minute after SW on to display and another minutes for work properly. Battery consumption feels little bit higher than I thought.

    First positive surprise: It arrived much earlier than I expected. Second positive surprise: it works as indicated. Simply plug in and press the On button for 3 seconds. I don't know if the values are accurate because I don't have anything to compare it to but, apparently, it's going really well.

    More than correct model for CO2 measurement Good results without the slightest hitch. Slightly less reliable when it comes to measuring humidity
