    I just discovered this also works as a fart alarm.

    Excellent sensor, we use it at home and when we go to hotels etc. It sometimes alarms CO2 when first switched on, but it settles down after a few minutes and gives a safe reading All in all, we're very pleased with its quality, price, and monitoring. The battery lasts around 5 hours in constant use. We charge it via our Xmund power station, also purchased via Banggood. I'd recommend it for anyone who wants to keep an eye on local air quality and also when travelling.

    That's bullshit. Reading from the flashlight, CO2 can jump to a critical value all of a sudden.

    The product is well packed. It looks quite nice and well made. The screen is visible in daylight, but not at all angles. The sensors react quite quickly. The alarm is loud enough but not annoying. The only problem is that I received a completely wrong product. I ordered this one from the screenshot, and got another one, which does not have a CO (Carbon Monoxyde) sensor, and that's why I bought that device. Anyway, as it is, it's solid for the money.

    A very good product. How accurate it is? I do not know but it is sensitive to gas composition changes.

    I can’t test the accuracy but it turns on and there are numbers for all 6 parts. Display has spelling mistake. “maderate”.
