This water softener works as advertised.  What more can you want?  The price was right and the install was a breeze... for my brother who had already installed his.  It does take some plumbing know-how.   He had it installed and ready to go in about an hour.   This unit comes with a device that lets you shut off the water with your phone.  You can also receive alerts to tell you if you have a leak.  It also shows you about how many more days you have before running out of salt.  
Overall, it's a great unit and I would recommend it to anyone who needs softer water.
