So weird to say that I love a shower head but, I seriously love this shower head! Such a great price for something that instantly makes my shower feel so luxurious! We tried it initially without the water saver piece, even though it felt amazing, California is in a drought so it felt wrong to be so indulgent. The next day we tried it with the water saver and wow does it really save water... to the point where water wasn't coming out of all of the holes. The best compromise we found was to drill a small hole in the center of the water saver to allow for more flow but not too much. 
Also love the S arm. It made the head the perfect height since our original piping is on the shorter side.
