This is just an amazing product!  I love it!  It really does change colors without batteries, it using the water pressure to change the colors.  It also has a very nice flow of water out of the head.  It was very easy to install, just simply twist on.  I had no problems or issues installing, it even has washer included so water leaks.  The colors are great, it was a blast taking a shower with the color changing lights, even my son had a blast could not get him out.  I highly recommend this product, it has a great flow and awesome lights.  Works amazing!!
