Bests & Worsts Reviews from Amazon

I'm 57 and have never bothered to review a product before. This unit deserves one. I bought this to replace an old shower head, in an old house, in a city in MA, that is now rumored to have the highest water rates in the USA. My wife has a daily shower at 5am, and the noise of the flow through the copper pipes, apart from waking me up (and making me wanna go pee) seemed to go on for ever. Another problem that we had is that, after about 2 minutes, the cold water in the mix arrived from the old clay pipe water mains which are about 10 feet down. In granite. In New England. In winter. It would suddenly (and shockingly) drop the temperature to tepid. I did not expect a lot from an economical unit such as this. This unit has: 1. Reduced the "pipe noise" level to where I thought initially my wife had given up showering! 2. Produced an increase in water pressure and rinsing action that allows my wife to rinse her hair in a fraction of the time. 3. Cut our water use bill by about 35% 4. Nearly eliminated the cold water shock problem described. In short, I was so impressed that my 1st thought was to buy a lifetime supply of these just in case they stop making them!
