Review on 🌬️ Smart Yellow Jacket ABM 100 Anemometer by Eldrick Carlton

I had no problems installing or using it, but the anemometer is useless! I've had instances where the app read up to 1000cfm and the anemometer blades were stationary. I've had occasions where I felt decent airflow and the blades didn't move. In some of these cases, when I blew on the blades, they began to rotate and measure the airflow, assuming there was a minimum inertial force that had to be overcome before the blades began to rotate; However, my overall assessment is that it's an imprecise measure at best - sorry, I don't usually give such bad reviews.
