This is so useful where i can turn on or off of using the Aromatherapy Shower which id say to everyone its so relaxing and a spa at home feeling. The way you can infuse essential oils in with your water is amazing the O - no fragrance, I - low fragrance, II - medium fragrance, and III - high 
fragrance setting's and it doesnt leave any oily residue on the tub which is amazing On the top half which we use more of is amazing it has 6 settings you can use massage, relaxing massage, wide-coverage, downpour, intensify and rinse. The kink free hose is awesome also the magnetic dock system is quite useful and handy when your cleaning. This is a must have for us mom's
