While the description says from 0 to 30m/s 0.1-0.2 etc., it doesn't measure, it goes directly from 0.5 to 0.8 and above, and in steady air it gives a different value each time........ That is, for measurements below 1m/s it is 100% unreliable.....if you want something cheap to measure air approximately or roughly with a large deviation, it's worth it. For accurate measurement at low values, it's a waste of money.

I bought this anemometer specifically to measure airflow in a chimney. The device does not have good sensitivity at low flow speeds, which practically means that you cannot measure flows below 1m/s (the manufacturer claims 0.8m/s).

Although I have it for only a few days, it seems to do what it promises. It is small in size, convenient for me, and I measured it compared to a more professional one where it showed negligible deviation. In a few words, it is worth the money.

Very good, it measures the temperature and wind speed in km/h and m/s, it also has a Beaufort scale with the bottom left button, you turn on the light for the screen. Overall, it seems reliable and well-made, and the little fan that measures the wind is very sensitive (meaning I walk and it turns). Finally, it does not recognize the direction of the wind, you have to turn it in the right direction for it to measure accurately

Very good, small and of course measures speeds over 30m/s. Bought it to measure absorption
