This product definitely does what it is supposed to.  There are bv 6 white noise settings some sound like what they are supposed to, some are close and otheres are way off. The buttons are a little louder than I prefer but that is just me being picky. Some of the sounds have avtendancy to be just slightly high pitched in my opinion but as previously stated still do what they need to do. Would recommend as a quick cost efficient fix.
