Review on HOISTAC Personal USB Fan for Desk and Office - 4 Inch Mini Fan with 3-Speed 360° Rotation for Home, Bedroom, and Computer by Amber Gonzales

I bought this fan when the temperature was over 100⁰ and just couldn't cool my home office. Pros: Easy to use (literally just one button), easy to position, fan head rotates and stays level. It's not too bulky and acts as a fan, blowing cool air around you. Cons: It's quite loud, especially on medium and high settings. When I answer a lot of calls I usually turn it off because it's hard to hear me.
