To start I would have to point you to my Journal-
IFM works very well on my moody mother, (not many other females I am around regularly enough to make solid notes on)
TUTH, very interesting results-
see this post in particular - 10 days with Androtics products - #8
IO- I just like, wear it almost daily. trouble is younger women (teens) start jabbering, chattering or chirping, just making noise talking, it sometimes becomes pink noise (oh that is a pun) (pink noise- is similar to white noise, which is pure random static or hissing, pink noise has some discernible sounds in it, pink noise is like an AM radio almost on a station, whereas white noise is completely between stations)
