This nozzle is much better than the various plastic nozzles on the market. You can easily control the water pattern by just twisting the nozzle. It won't corrode since it's brass. I've had the plastic before and they always seem to eventually go bad.
This really is a SOLID BRASS nozzle not one those aluminum ones that are made to look brass. It works great and will be buying another one for the back yard hose!
Best nozzle made!
No probs with rusting, or corroding. It will change color, but that adds character! I've had several of these over the years, and I usually replace the hose before the nozzle!
