I paid the customs duty. The seller cheated, saying that the price in the declaration was $ 30, in fact the prices in the declaration are higher. I give a low mark to the deal for lying in correspondence. The device is normal.
Shipping was pretty fast and item well packed. CO2 sensor is fast and precise. TVOC value is very dependent on calibration and I am not sure if I am getting correct values. Temperature reading is good enough for me. LCD not very good quality, but is visible from all angles. Not suitable for bedroom at night, because of bright lights and always on LCD screen. Also PM sensor fan is audible. Wifi connection works and I can get data into Home Assistant. When I have time I'll put info onto github on how to do that (basically add to wifi via airkiss and capture UDP broadcast).
