The Mainstays 20 in Box Fan FB50-16HL is a corded electric box fan with five blades and three speed settings, built for moving air in bedrooms, kitchens, basements and garages. It has stabilizing feet, a built-in carry handle and cord storage, so it is easy to move and stow. Against rivals it is a basic, low-cost air mover: it does not oscillate, has no remote or timer, and is not a window or exhaust fan. Owners rate it well overall, with most complaints about noise at the top speed and airflow that is modest for a 20-inch fan.
