Excellent Box Fan. Will Keep you COOL!!😎

Excellent Box Fan. Great for circling air around, especially if you have a room that doesn't have a ceiling fan. Living in Florida you need fans even with air conditioning. Works great to keep your electric bill down so you can turn the thermostat up a few degrees %26 use the fan to circulate the air, which makes it feels three to five degrees cooler.

Love it

This is such a beautiful color, added a nice pop to my bedroom. Classic box fan sound, love it! Adds a nice air flow and circulates the air nicely. The only odd thing is when you turn it on, it starts on the highest setting which I thought was weird. Other than that, very good quality and price.

LASKO FAN

Got my new LASKO FAN at a good price. It isn't noisey at all. I got the white with grey panel. 3 speeds to choose from. Came with legs to keep it from falling on the floor. Blows cool on the floor with windows open and i got it on 1. Happy with my purchase.
