Easy installation with a few simple tools, as long as you are comfortable with installing compression fittings and t-valves. Instant streaming hot water is nice. A couple of small issues- sometimes the button for dispensing water doesn't close the valve completely, so the water drips until you press and release the button again. Also, the first week or so, the water had a plastic-like taste, even though I flushed the system as directed. The taste seems to have gone away since then, however, and overall I'm happy with this unit at the price point.
