Cheap material. You get what you pay for. Used this for about 3 months. One day, the cold side nut connection bursts open during the middle of the night. I change out the o-ring, and that fixed it temporarily. But I did notice that the malefemale connection pieces were starting to rust. Couple days later, the same thing happened to the hot water side. Why Because the connections were already completely rusted and burst open… this product is absolute garbage. Everything about it seemed pretty cheap when I first installed it but it looked great so I gave it the benefit of the doubt. But I should have trusted my instincts. I have thrown this one out and replaced it with a better quality shower system. DO NOT RECOMMEND!
