Q: If you already have the DeWalt batteries his is a great addition. This fan is so convenient to use that I end up using it all the time. It moves an impressive amount of air while at the same time is quiet. A 6Ah battery runs for over 10 hours on high.

A: positive
****
Q: Awful product. It changes and appears like a chemical solution after using for couple of days. This product doesn't seem authentic. Please don't waste your money.

negative
