Review on Convenient Clip-on Portable Stroller Fan: Rechargeable USB Mini Desk Fan for Versatile Use - Ideal for Bike, Bed, Car Seat, Camping, Bedroom, Kids, Baby - Black by Rachel Smith

I was a bit skeptical about this but decided to write a review after coming to my home office for the 3rd day in a row and it could not find my fan. My son and wife keep stealing it for their desks. It has 3 speeds that can be easily switched with a single push of a button on the back (long press to toggle on/off). It has enough power that I can't crank it past the lowest setting on my desk. (My son turns it on and straps it to his leg while playing Mario, wish I could add this pic.) Battery life is good; At the time of writing it is still on its first night charge.
