Review on Stay Cool and Hands-Free with the Portable USB Rechargeable Waist Clip Fan – 8000mAh, 6-32 hours Working Fan Ideal for Travel, Outdoor, and Office by Kino Gerami

I took this to school and used it outside in the sweltering Miami heat. My first impression is that he is: 1- Well built. It's a plastic case, but I don't think it will break in my hands. 2- It's a bit noisy. There is a noticeable hum even on low settings. It gets very loud on the highest level. 3- Nice clip design. Can work on a necklace if you are creative. The real problem is the noise, especially when you're talking to someone face to face. Basically it works as described.
