I have to say this fan is worth the money. The fan blades are not 100% straight and I have found that this causes them to vibrate at high speeds. But being able to use my Anker portable battery doesn't bother me. Blows air, quietly on low or medium settings, blows in the direction you point. Again, it's worth the money and I'll be buying another one before summer and I can just run them on my test and not worry about getting a high score.
