These sell upwards $180+ per copy. (Home Depot is 145+tax). For that kind of money it's a rip-off considering the few parts required, and the poor, flimsy quality with inappropriate choice of materials. (All seals of the hot water path should be silicone - they're NOT, they fail first.) They last (in my case) about 3-4 years (tops) but we're not heavy users. (Compare to that a Pfister kitchen sink faucet's quality for $150 or thereabouts; in that comparison InSinkErator HOT-1 is pure JUNK).I wish there was a rip-off copy from China, for half the price; InSinkErator people deserve to be copied and bankrupted. If I find an Asian copy, it's GONE.
