Great hose. This is my third because the only downside is that the area connected to the spigot can crimp and ultimately leak. It’s easy to keep that from happening if you are the only one using the hose. But if others, like your kids or a garden helper use the hose, they don’t always recognize that.

Weak but excellent please read.

Size: 50ft, Color: Black

Breaks a lot, but Is 100% convenient. My third annual purchase. Beats rubbing stuff off of twisted rubber hoses. Darned if u do. Darned if u don't. A 5-10 yr version one of these will outsell the entire market.
