I have had this 1.5gpm unit for going on 2 years now. It is wonderful to say the least. The shower is very strong and the way the system force feeds air into the stream to speed it up makes it more enjoyable and better at washing soap off then the old 5gpm unit I had. I have been purchasing them for all my friends and now they are stating to ask me where to get them. All their friends now want one. Outstanding product.
