Review of my new fans
Oh wow! This is the best fan I have ever bought that works and looks this good. And their customers are who they work 4. My air conditioning went on the blink so that's why I needed them. But I made a real good buy. Thank y'all for all ur services. And this old lady loves y'all

Great box fan
Another great fan this one's a box fan and I promise you low is about all you eat. I use it to start my vegetables inside and I use it to blow the window. I'm just strengthening the stocks and to make a stronger one before you put them outside that works really good. I like it so once again, thank you Walmart.
