I love this fan and it works great!!

I really like the size of this fan. It's small enough to fit in a large purse of tote bag without taking up a lot of space. It has three speeds and can sit on a table-top or be hung from a hook. I also like that it runs off USB or 4 AA batteries for easy mobility. A friend of mind had this and I had to have one. Also purchased one as a future gift for someone. LOVE IT!!!

Mainstays New 4" On-the-Go Folding Personal Fan

I have wrote a comment three times, keeps getting knocked off. Love this fan, bring with us on our away from home, can use batteries or electricity. Perfect fan for standing up or putting on items to keep two people comfortable with air ventilation in high speed. Only complaint, I ordered two, took seven days to find out, there was a problem, will only receive one. Still happy to get one, but disappointed in Walmart's accountability for available. Definitely grade this portable fan a 10. Will wait next year to get one more. Compactible to carry with me on motorcycle trips staying overnight in hotels.

Great Fan, but needs batteries for "on the go"

This is a great fan, and puts out a good amount of wind. The included cable is pretty long too. My only complaint is I wish it were a rechargable fan. If you want to take it on the go, it uses regualr batteries, it doesn't have a built-in battery. Besides that, love it.
