Very good quality but... after about a week if you don't lubricate it with grease, the rotation becomes difficult due to rust salts?.... regardless of pressure up to 4 bar, so if you lubricate it often and keep an eye on it, everything is fine

One and a half stars..... I have bought 3, I install them, and after a month, they don't rotate. It seems that while they used to rotate relatively easily by hand, now they have become tighter, obviously due to salts or internal rust....... on the contrary, the plastic aquabax that I had for throwing away works fine
