Delivered very quickly. The product corresponds to the description. Very high quality. I'm happy. I recommend. In the kit to everything was also great. Follow the instructions. Cut the ring on the neck, fill the bottle with water, twist the dispenser slightly until the stop (remember! This is not a metal design), screw, pour on the bottle to make sure the tight twist, install the whole design, make a holeat the top of the bottle, adjust the dispenser. And a miracle!
