Cheaply built - 3 of 6 were defective.

We bought 6 but are having to take 3 of them back, one will not run when you set it to high. The other two’s back screens keep falling off. Hopefully they’re just duds and the replacements won’t have problems. They were a good price so we had high hopes and expectations they would work, so a little disappointed.

Good value, best at lowest speed

The fan looks nice, the frame is sturdy, and the fan and motors run great for hours each day. I think the lowest setting is best for me because it is already powerful 10 feet away and anything higher is loud enough to disturb my gaming with headphones on. Also, at medium and high speeds, my fan blows itself out of position on wooden floors so it needs something extra to hold it in place like rubber feet or something.

Using in the window!

I have a box fan similar to this one that I love. I live in an older home and hesitant to put in a window ac in my guest bedroom window.Remembering my childhood I thought this would be a perfect solution in spring and fall to secure in the window.I haven't used it yet but excited to use it soon. I redecorated this room 60's style so this should fit in perfectly!

Parts missing/broken

Bought 2 of these. When received, one of them didn't have screws in the front grille. One foot was broken. The other would not turn on. So i heard a hum. When i smacked it with my hand. It started slowly then sped up. We left it run for awhile still working. But seems to be a lot of problems with just having 2 of them. Oh well i put screws in the one. I guess they'll be ok. If not for the problem. Would've been 5stars...

Great Box Fan!

I ordered this box fan through Walmart.com. I could not beat their price! I went on Lasko’s website and looked at all of their fans. I have owned some of their lower end box fans in the past. This fan is so much better. The seller was outstanding. Fast shipping.

Works amazing! Cools a room down quickly. Even quicker for a darker room.
