This is one of the cooler gadgets I've gotten my hands on in recent memory. I set it up on the sink in my outdoor kitchen which we often use for cookouts and lounging by the pool. We have "outdoor/pool" cups that are used for beverages, so being able to thoroughly rinse them out quickly and fill with an new beverage or put back on the rack is great. Everyone who's seen it has told me how cool it is too. Works exactly like you think it would. You do need some basic handyman/plumbing skills to install though or watch some videos to learn. The two pictures are of the hose attachment to the water line and all the tools I used.
