I was curious about this product, because I live in a motorhome with both an indoor and outdoor shower facility. As such, their shower heads are, well, very cheaply made. Some ten plus years old, the range and effectiveness of their flow pattern adjustability was weakened with clogged orifices. The inside head appeared to suffer from build up of minerals from hard water, and the outside, from that, and a tendency to acquire algae coatings, if unused for long periods. Normal cleaning methods don't free the holes from any of that, and I can imagine, more difficult clogs from any larger contaminants in the water.Unlike the shower head featured in the product ad, there are two different spray methods in my heads, one for true shower, and one for massage.
