This shower is just great; it has 3 jet systems: a jet "massage" (Whirl), a powerful jet "water + air" (RainAir) and normal jet (Rain). Each of these jets is much appreciated !!! I regularly pain in the neck, and since I have this shower, I use the jet massage and frankly, I feel an improvement; the pain is felt less often, and when present, they are less intense! The RainAir jet is also very nice for both rinse the shampoo on the hair after an intense day, where we returned tired ... it's invigorating jet! The special anti-scale system is effective. I can only advise you.
