Review: This thing will self destruct - The product worked for a day, and then literally blew up.. the thing came apart and caught fire, and water was going everywhere.
Review: Does not get to temperature for a small sink - I would HIGHLY recommend looking for a different unit. I tried this unit for a under the sink water heater and the temperature never got about 79 degrees. If you barley turn the water on it will get to 120 degrees. Save your time and effort look at something else.
