Would you buy this if you don't have any wfp's or would you skip it altogether?

This is ettore 6ft pole when extended that you can hook a garden hose into and it feeds water through the pole. Is it garbage or worth it? It's $20 at lowes and I get a 10% discount. I am just starting and haven't done at residential yet so I was curious to its usefulness or have any of you tried to use this cheap kind of pole yet?
