This would be a great product if the part that connects to the shower pipe was made of metal instead of plastic. According to the instructions, you are to use a wrench to put the part on even though you are screwing plastic on to metal. I just used my hands to put the part on and it cracked (even though I used plumbers tape as instructed). I went to home depot to see if I could find a metal replacement for it, but they don't sell them. I did however find a plastic replacement which I purchased for $5. I like the product itself as my skin and hair feels better and soap lathers better, however they could have made the part that screws on to the metal shower pipe METAL instead of plastic. Poor design.
