Has Anyone Tried These?

Mini Bladeless Fan Today's Save:$27 for a bladeless mini-fan + free shipping — four colors available!

I like the look of these fans, and I'm curious if any of you has ever tried a bladeless fan before.  We ALL have a fan in our bedrooms, not just for comfort (save on A/C overnight!) but also for the white noise.  Do these make the same white noise that a fan with blades does?
