Yeah, I've got a few of them.
I use 3 of them in a 4x4 and they move air very well. Only grumble is that after their first grow 2 of them started making a lot of noise when on oscillate. The fan motors themselves are still as strong and quite as they were when brand new, just the oscillation mechanisms are shit.
Looking back I should have put them on an alternating on/off cycle to give each an 8hr rest each day, rather than run them 24/7 like I did ...actually now I think about it, I'm pretty sure AC Infinity mentioned that somewhere in their literature
.
It's a bit disappointing, but not the end of the world. They still shit all over any other oscillating fans I've had
