Exactly as advertised. It's a sleek, stainless steel glass rinser, and it does its job well. We went to Harry Potter New York, and the butterbeer bar had glass rinsers like these. My kids thought it was so cool, and they kept talking about it. I went online to find out what these were, and I was surprised at how cheap it was, so I decided to let the kids have some fun. It was easy enough to install, and its easy to use.
Just take your cup and use it to press down. You don't have to press down too hard, and it's not so light that you just touch it and it shoots out water. It has multiple streams of water so that it cleans the bottom and sides of the cup. It leaves the inside of your cup as if you never used it. My kids will do the dishes now or at least the cups ?? Love it!
My only issue is that the handle is too close to it, so we have to turn it a little when the cup is wider. However, that's my own sink. Just make sure to check!
