Very pleased

I bought one of these to replace an old shower head, not really thinking it would make any difference to the pressure. However... its amazing the pressure has noticeably increased, we can now actually feel the water. We tend to keep on the normal setting but the jet one is great, feels like a massage. We also purchased one for my Father in law as he had commented on it when visiting. They have an electric shower which is so weak you get wetter standing outside on a hot sunny day. He says it's made a huge difference and is over the moon with it. Not quite sure how these magic stones work but they do!
