During the heat wave I order USB fans, this model is the cheapest of what I chose. but, Oh Surprise !! he turned, blew so hard, he advanced alone. I have stalling. he walked the divine end of gods !! But after two weeks of intensive use (I want to clarify ... + 24 hours to sharpen, sometimes ...) he start blowing less strong. Now wriggle tournament, he always refreshed a little bit. But for the price and the urgency of the situation, he fulfills his office. If next year another heat wave is announced I re-take, and will protect the curious who plays with when I leave my office.
