Review on Optimus F-4092: Ultra-Durable 9-Inch Industrial-Grade Fan- Silver Coated, 2-Speed - Buy 1-Pack Now! by April Irvin

Used this fan probably 5 times The fan does not have a top/back handle like other fans. Gripping the grille or any other part is unsafe or uncomfortable, and the best way to move the fan is to turn it off. Also, I don't find much of a difference in airflow volume/speed between the two speeds. Sometimes it makes an annoying hum and other times it sounds shaky. Everything around it is badly designed. I've had similar fans over the years and they've all been better, which this one lacks. . However, I bought an even cheaper Honeywell fan with a hard plastic case and it works great! Handle, 3 speeds, quiet, pumps air, looks normal. A good product does not always depend on the price. I recommend the forced air fan type as even a small model seems to push the volume of air efficiently. Select the fan size according to the area of application.
