    Good store and good product.

  3. Customer

    works well, good quality.

  4. R***k

    Works well. Needs English instructions.

  5. C***r

    Really accurate and good PM2.5 meter. I have sat this next to my AWAIR2 air quality monitor and the readings are very similar – allowing for the fact that each meter is monitoring different pieces of air.

  6. D***o

    No English manual included. Can’t understand how to operate. No charging cable included. Always shows 6-8 air quality even if the air in the room is dusty and bad. Don’t recommend buying. Seems like a waste of money.

  7. G***u

    Что я могу сказать – в Ирландии чистый воздух! Периодические проверки указывают, когда пора прибраться в комнате или проветрить помещение. Сделан качественно. Думал, что будет тяжелее, а так лёгкий, словно полупустой внутри.

  8. P***V

    Все как и всегда оч качественно + оч рад, что встроенный аккумулятор, не нужно покупать батарейки) до конца не совсем ещё разобрался, что именно он измеряет, но судя по показаниями воздух почти чистый. Спасибо продавцу за быстрое отправку, посылка пришла за 2 недели.

  9. Y***n

    The effect of air quality is punctured on the device
