First time having and installing a water softener. This product was super easy to install and set up is a breeze. Only potential downfall I see could be the way the pipes are held on using clips. But I guess if it's just sitting there they really can't go bad. Have had it installed for a weak with a starting hardness of 250ppm. Currently the unit is at 40 percent so I expect it to do it's first auto regeneration this week!
