I appreciate how much time I save with this Delta cup rinser. I tried it with cold at first and it works, but old coffee rings can be stubborn. So, I switched it to hot and it works even better. It took only about 20 minutes to install and was straight forward. Everything needed was included. My sink even looks better now with this cup rinser compared with the old soap dispenser that never got used. Porcelain and ceramic don't make much noise when rinsing, I have some plastic coffee cups though that are very loud when rinsing. So it just depends on the cup material what sound you get. It is stainless steel and matches my sink perfectly, I am very happy with it. Anyone could install it.
