Has anyone used an electromagnetic water conditioning/softener system, such as Soo-Soft or EasyWater?

Here's some interesting research from scientists who "question" the validity of these "dubious" water treatment systems.

"This page profiles water-treatment schemes other than those involving magnets or magical "catalysts". All of these I consider "dubious" in the sense that there is no credible evidence in the reputable scientific or engineering literature that these devices work, and in most cases there is no reason, based on present scientific knowledge, to believe that they even can work.

We have a ScaleWatcher 3 and love it! It truly works great! The company has an A+ rating from the Better Business Bureau and gives you your money back if it doesn't work! The unit is guaranteed for 10 years! We were very sceptical at first... but it really works great... keeping our Corian white kitchen basin clean and keeping the toilets nice and easy to clean. Shower and bath water feel excellent! There is scientific research showing that magnetic conditioning works, such as by Coey and Cass. This electro-magnetic unit works far more efficiently than to the simple, cheap solitary magnets. The company even makes a lot of huge units for industry. We love it!

The most common means for removing water hardness rely on ion-exchange polymers or reverse osmosis. Other approaches include precipitation methods and sequestration by the addition of chelating agents. Devices which use magnetism or electrolysis as a water softening technique claim to inhibit scale build up without actually removing hardness ions from the water. Hard water can be hard on both your house and you. Take the edge off with Culligan home water softening systems. Each is designed to help reduce water contaminants, scale build up, and electricity use, plus extend the life of your appliances, deliver better-tasting water, and make cleaning easier from sparkling dishes to softer laundry and more.
