I rated ease of installation at medium because my plumber did the install, along with a filter and a faucet. Looked fairly easy (but I can no longer get down to work under a counter, so what do I know). Anyway, the hot water dispenser is great. Very handy for making tea without the microwave or kettle. Tried instant oatmeal... not quite as good, but I'll try again, Super for quick rinsing things without wasting water waiting for it to get hot. The design and finish of this item well matched the faucet and soap dispenser from a different vendor.
