During my bathroom remodel I searched for a rain shower head with a handshower attached that wasn't horribly expensive. I then realized what I wanted my parents had installed a few years earlier in their bathroom and loved the product. A quick search brought me to the pulse website and another search brought me back to wayfair to actually purchase the product as the price was competitive and I think I received free shipping. One note is that I received the Kauai rain shower system 3 not the 2 as I was expecting and my parents have installed. With that being said I have no idea what the difference between the two are and am very happy with this purchase.
