we have only had our softner for 5 days and we are so pleased with it we would by another one.This is the best thing we have ever purchased for our house.We noticed the differance immediately.Better water cleaner ice and better showers.No calcium particles floating in my drinking water glass.This has been a wonderful experiance even on installation.Very professional group to deal with.I can't say enough about this company.They even financed it for us and that's a big thing when your on disability,otherwise we could not have afford it.The installer went over every aspect of the softner with me and explaned everything to me.Needless to say I was not left in the dark when the installer left my house and thats a big deal to me.Thank you so much for ringing my door bell and offering me a free water analysis.
