    Good product but its power adapter is defective. After half an hour of charging, the power adapter was burned. In addition, I got a detector described in Chinese and I live in Europe. Someone did not think.

    This tester provides very clear results based upon its assessment of particulate, Volatile Organic Chemicals, and formaldehyde concentrations in the air. It also provides temperature and humidity readings. My only reservation is that I don't have any other devices to support or dispute this machine's results.

    Il principale problema di questo apparecchio è che è completamente cinese ma ciò era chiaro nella descrizione pertanto non ci si può lamentare. Performace delle misure. Temperatura è allineata a quella di altri termometri pertanto la considero buona Umidità misura circa il 15% meno di altri apparecchi lo considero scarso Formaldeide: non ho metri di confronto senza voto PM10, PM2,5 VOC: non ho strumenti per valutarlo ma le misure hanno un senso esposto ad ambienti "polverosi" le misure aumentano e in ambienti sicuramente puliti diminuscono: voto buono fino a prova contraria. Radiazione elettromagnetica: misura un valore fisso solo se collegato all'alimentatore altrimenti segna sempre 0: voto scarso. Batteria: ha una ottima durata voto buono. Alla fine un apparecchio con luci ed ombre, forse un manuale in inglese potrebbe togliere qualche dubbio, ad esempio il tasto di zero a cosa serve? Lo stesso apparecchio sempre in versione cinese su un noto sito di vendite online era molto piu' costoso

    When sending a product to the EU, it would be good if the user manual and power supply were adapted to EU standards? I can to some degree understand what the individual gauges tell, but only about half of them.

    The manufacturer seal on the item I received was already broken it seems this item is either refurbished or a returned item. I have kept 3 devices including this one at one place. The temperature mesurement is with in the range but the Humidity measurement is way off the mark.The other readings also does not seems the correct.

    Not working well at all. Erratic numbers, totally inaccurate. Compared with other testing units, this is absolutely bad.

    Humidity factor 2 to 3 to low. Radiation severely influenced by own charger and always 0 (even close to wifi/3G antennas) without charger. PM2.5/10 always the same value. In short: total disfunctioning device
