[EX 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.
[EX A]: positive

[EX Q]: Beautiful color! Wonderful fit! No, they're not SUPER-soft--but definitely soft enough. Just like the percale sheets I remember from my youth, they've a 'crisp' finish & don't make me sweat. They might soften the more they're washed, but I love them now, having been washed only once. Amy wrinkles flatten out when put on the breed. And they even fit my mattress pocket!
[EX A]: positive

[EX Q]: This was the 2nd one I had to order because TSA made me throw the 1st one out. Unfortunately, this one didn't even last 2 months before it fell apart. I don't know what happened to it but something inside broke; the slide switch no longer works. I definitely won't be purchasing this one (or any other like it) again.
[EX A]:
negative
