The Handheld CFM Anemometer has received mostly positive feedback from customers. They appreciate the sensitivity to air movement and its ability to measure wind velocity accurately. Customers note that the unit comes with everything needed, including batteries and a screwdriver, and that the instructions, while basic, are adequate. Some users found it convenient for checking furnace duct flow and measuring wind velocity for model RC planes. However, one user mentioned the need for a feature allowing the last reading to remain on the screen for a few seconds before it shuts off. Despite this, most customers are impressed with the product and find it to be good value for the price.
