I got this fan since my coworker has the same one and it worked so powerfully for her. I love it!
You get what you pay for. $8 one pretty good. $29 one really good.
When I opened the box it wasnt much to look at, but soon as I pluged it in I was blown away, and that was just on low, the 4th speed will move my curtains. Very powerfull little fan. Dont let the looks decieve you, this fan really blows, PUN INTEDED :)
They are ok
