Title: like a jet engine
Review: unfortunately, just too noisy. it's barely tolerable on low, then just for short periods. on high it's like a jet engine.[there's no whine, though, as another reviewer noted - just white noise. if it is whining, there's something wrong.)it's a nice compact design that seems to work well, if you have some out of the way room or place to use it where the noise isn't an issue!
