I am not someone who typically endorses any products but I have been using the Shower Clear shower head for a couple of weeks and I am very pleased with it. I open it up after using the shower and all the water pours out; I leave it open until I use it again. Although I know that the bacteria that causes MAC is everywhere, I am satisfied that I have reduced or eliminated at least this one source of bacteria. I was initially scared off by the price but that quickly faded when I started looking at shower heads of similar quality and price that did not provide an option for drying the shower head after use. I know that it is easy to become overwhelmed by the sources of MAC and (for me) the wish to "MAC proof" my world but I know this is not possible or healthy, from an emotional and relational perspective. Therefore, it something as simple as a shower head can help me reduce my exposure, it is well worth the money. As an aside, it is really solid and well made - simple and does what it is intended to do.
