This fan is very strong, even on 1 it blows a lot of air, at first I thought it would be too loud, it's not the quietest box fan however my boyfriend said it makes good white noise, I was skeptical, but then I fell asleep in about 2 mins so I guess he was right. Normally it takes me 15-20 mins to sleep. Overall a good buy especially with the free shipping option, low profile, very strong, the little plastic feet that you have to stick in for stability were unexpected but simple to use. I think you can get cheaper fans but I don't think they are as powerful as this one. Will be very useful in the hot summer months. Pleased with Amazon's awesomeness and pleased with this fan.
