We love having this hot water dispenser. It is perfect for getting instant hot water for making tea and other beverages. We no longer buy expensive individual pods for tea and cocoa. We even use it for foods like instant potatoes and instant oatmeal.. 
Dispenser is easy to install, though you will need to buy 1/4" compression washer and nut. You may need a plumber to figure out how to tap into your hot water line (I already had a separate valve) 
You can easily set the water temperature, but don't hold your finger under the faucet to see if it's hot; it is!
