It's a go-anywhere fan.
The fan is very very quiet so it is not a good sound for white noise but it moves air like a big fan so I kept it.
I live in Florida and I purchased two of these (one for me and the other for my husband) if the power goes out due to high winds in hurricane season.
Been having power outages where I live for over 9 hours each time and always at night...been warm and humid...but I was have my central air one but that only lasts for so long....but my main issue is I CANNOT SLEEP WITHOUT A FAN PERIOD...so I am like I AM GETTING A BATTERY OPERATED FAN FOR NEXT TIME...guess what....this fan is perfect.
This fan is powerful.
I used this fan 2 times.
Worked great when it was plugged in, but did not work at all as a "portable" fan.
Fan lasted two months, motor siezed and no longer works.
After one week it won't work with batteries and will only work on low speed while plugged in.
I used with battery first time and all the D size battery ran out of power after two day use.
