In our area we have very hard water, and my old system was a Whirlpool system that actually lasted 10 years.  When i was told that I would only get about 5 years out of any system, i decided to do my research.

For the price, and control, and wireless option, this system for them money was way more than i expected.  I have a family of 4 and also my mother-in-law staying with us while she builds her new home. 

After connection, and draining the old water from the water heater, i immediatly could tell the results.  Now, again, my last system was GREAT for my family.  No hard water stains, no plumging issues, not that would lead you to belive we had hard water. BUT THIS SYSTEM FAR EXCEEDS my old system.   HANDS DOWN. 

SO much so that my mohter in law, has already taken the mesaurments for piping into her new home. 

You can't go wrong!!!
