Review on Powerful and Sleek: Comfort Zone CZHV20S 20-inch High-Velocity Slim-Profile Drum Fan with Aluminum Blades and Adjustable Tilt by Lori Uniacke

I expected this fan to move a lot of air, especially with 5 blades. Although it's high speed, it doesn't move as much air. It's very noisy - like a propeller on an airplane. I tried using this at my home gym where my radio was playing music and the fan muted the radio so I couldn't even hear the music - it's so loud. I tried to return an item during the extended COVID returns period per Amazon's policy, but the seller denied the request. I bought a $50 Commercial Electric 3-blade fan at a hardware store, which is much quieter and has much better airflow.
