I really liked the Hotelspa 7 setting Rainfall Shower Head. All I needed to do was simply unscrew the old shower head and replace it with the new HotelSpa Shower Head that I received. I was then ready to start enjoying my HotelSpa shower head. It has the 7 different setting to use and the size is 7 inches. Using the shower head, was a delightful experience, was like having my own spa in my own bathroom. One of 7 settings is a pause function, that I really like as well,When I am in the shower lathering up my hair, or shaving my legs. I know that I am able to save water, and money at the same time. Then I can turn the shower head back on and enjoy those other different settings, which are : Rain, Massage, Mist, Rain and Mist, Rain and Massage Or Economy Rain and also Pause feature that I had discussed earlier. If any one of you are having to watch,how much water you are using or in you live in a restriction area, this would be perfect for you as well as anyone who just wants a Spa like Shower Head. I know that I will be enjoying my HotelSpa Rainfall Shower Head for a long time for sure.I received this product for free for my unbiased review and my review is solely my own.
