Really I did expect a piece of junk for the price but it works so well that it did not stay in my possession but for a day before my wife claimed it. I would have given a 5 star rating but the ups cord was missing.

Superb Tiny Fan

This is a wonderful product. Has 3 speeds and the included rechargeable battery seems to have good power. It also attaches to any other USB external battery or computer device to run it. Which is handy out in the field. Good power for a tiny unit. Seems well built also.

This little dynamo has worked from the moment I began using it. I love the rechargeable battery and the power is unmatched by other models of its size!
