Very happy with this product to use. Very easy to use, adjusted the different jets by turning the shower. All jets are distinct. After a few months of use, I see no limescale or variation in the jet power. Only drawback, when the use of the most powerful jets temperature of the water decreases. The full stop function jets is very effective and convenient especially if the water temperature setting is not done with a mixer. There 's no leaks during the use of this function. Very good recommendable product, 1 star less for the plastic look of the handle, very robust despite this. Excellent price / quality ratio.
