I was not sure how this fan would work but decided to give it a try.  I had never heard of a fan with retractable blade before seeing it on wayfair.   I needed a fan for a small kitchen area that gets a lot of sun light and warms up and liked the look of the light fixture.  The fan was an excellent choice for the space.  It generate excellent air movement and the styling was perfect for my kitchen.  Ive now installed two.  They are very cool!
