I am selling this item because my family purchased a different one on the same day I bought this. I only tested it once to see if water would come out, and I have not used it to wash my body in the shower. I have not used the included adapter either. Since this is not a brand new, unused item, please refrain from purchasing if you are overly concerned about its condition. m(_ _)m To prevent product substitution, returns are not accepted. Thank you for your understanding! This showerhead uses nano-bubble technology for high water-saving effects and is gentle on the skin. - Model Name: Nano-Bubble Showerhead Premium - Water Flow Type: Water-saving type - Warranty Period: 2 years
