Great product does what is expected. 1 Star deducted for the fact that this unit literally takes hours to get the cold water cold. Manual says 1 hour at start up and I initially thought and still might have a defected unit as it takes 3-4 hours to get the water cold before the light goes off. Did temperature checks and both hot and cold are where the manual says they should be but cold takes forever to reach that temperature. Only time will till if I have a defected unit and hopefully if it happens if will be in the next few weeks within my return window.
