Review: Great fan with 3 speeds. Light weight and rechargeable.
Review: I noticed this fan around the neck of an associate in one of my favorite stores & asked her about it. She highly recommended this product, admitted she was sweating a lot especially from her head/face (just as I do) and told me the brand and where to buy it. The package arrived safely packaged, with clear instructions & charging cable. After a full charge I tried it out and was blown away (lol)! All 3 settings work as advertised and help keeping me cool. It also helps me keeping my air condition at a reasonable temperature & my energy cost down. Excellent product, comfortable to wear with adjustable cord, lightweight and good looking. Yes, I highly recommend this reasonable priced personal fan that exceed my expectations.
