This is the third InSinkErator instahot I've purchased and installed (Other two were left in previous homes). My wife and I drink instant coffee and hot tea. This works great for that, along with other needs for hot water.
This purchase was for the model with push-button activation. This works better than the model with the lever.
Very easy to install and comes with all the needed installation parts. According to water supply location, you may need a little extra 1/4" copper tubing.
