    Arrived pretty fast, the whole thing. It looks nice and neatly made, complete micro-usb cable. Plugged in to the usb charging, got it all working, charging went. A few minutes later, the readings came in. It turned out that the air in the apartment is quite edible) In the package brochure with the pollution standards. If simple - then the lower left indicator shows the overall air quality - 1 is the best, 6 is best not to inhale.

    Nice device! It arrived quickly, very well packed, just as the propaganda said ... but while in the BangGood advertising it said verbatim "Accurate detection, high precision and nice stability.", in the manual it says "This tester is a household product, the test data is only for REFERENCE, and can not used as any basic data ", I think we can then speak of misleading propaganda.

    Excellent tool for measuring Formaldehyde CO and CO2 and chemical pollutants. The CO2 sensor is very sensitive to any change if you exhale towards it the CO2 reading almost immediately responds to it. I'm very happy with this product and can truly recommend it.

    Cons Battery only lasts an hour or so. Best left plugged in. Often goes crazy high readings and needs resetting. If you fart again it goes mad and need to press reset. Pros Generally good enough to let me know some idiot nearby is burning mattresses. Shows high formaldehyde levels in my annex with new foam backed carpets.

    Retro design with 3 akkucheck LED and LED numeric display, which hardly visible at outdoor. First counting 0-120sec on the CO display while sensors heats up. After 30 minutes measuring it goes to standby, display off, only 1 akkucheck LED remains. It works 4,5 hours with a full charging. Reading are credible and good reaction after opening the window.

    A very interesting unit, takes quite a bit of time to warm up, but when it does it shows real time CO levels, windows opened or closed show what you are breathing. Recommended for those who care about their environment.

    I have compared these values ​​with those of a professional system. I am amazed how equivalent the test values ​​of this inexpensive device are.
