We couldn't be happier with the ease of installation, its size, and it's effectiveness.  Salt consumption so far is reasonable - having dropped from level 8 to level 5.5 in about 30 days; machine estimates approximately 75 days when full.  Our water sample testing revealed this softening system to be completely effective in removing the minerals that have given us hard water for so many years.  This was very significant in reducing our skin irritation and discomfort.  We immediate saw/felt a difference in the cleanliness and softness of our laundry.  Showers and baths feel great.  Water tests also revealed a more balanced pH level.  There is no strange or salty taste to the treated water.  We are very happy with its ability to support our whole house's demand for softened water.
