Very easy to install,  and the 5ft length is really nice.  It comes in handy when cleaning the shower, giving the dog a bath. The multiple settings are also wonderful.  They are not as powerful as I hoped,  but am not sure if that's an issue with the water pressure we get or not.  I still can't decide which setting I like best,  but I use the strongest for my lower back, especially after a long day when it is bothering me.
