Title: Poor Quality
Review: This is a replacement for an older model H990 unit that was dying after 10 years of use. The upper portion of the unit is identical, but the undersink heater unit appears to be made of plastic, not metal, like the previous model (which had a copper tank enclosed in styrofoam enclosed in sheet metal). Notably, the other unit ran silent but this model--which you think would be an improvement--makes a very noticeable "roaring" sound when heating the water, audible over a low TV or conversation even from under the sink. Also, the water out of the tap is about 30 degrees cooler (170 vs. 200) at the "factory preset" thermostat setting. Product description on Amazon is confusing and contradictory: is it a 1 yr or 3 yr warranty? 120 or 115 volts? 2/3 gallon or 1/2 gallon tank? It gets the job done, but it's the little things like this that give the impression of diminishing quality from the InSinkErator brand, and at this price point you expect more.
Is the review positive or negative?
