Mira Eco Shower Head

Ordered the Mira Eco shower head online in good faith, to save water & water heating costs, after quite some research. However, within seconds after fitting I stopped the shower as the noise was incredible - could not believe how bad it was! Sadly it seems this is part of the water aeration process. Fitted the flow reducer which did stabilise the pressure & reduce the noise a bit, but not sufficiently for me to want to keep the unit. It also, obviously, badly affected the pressure. Within 24 hours it was in the post back to the supplier for a refund. I am disappointed that an outwardly great idea, from a very well known & respected manufacturer, has such a drawback & that few people seem to have reported this - or have their views been censored on other websites?????
