We have been using two of the Hardness Masters for a year now with great results. As an engineer I had experience with the technology in a plant but was leery as our plant system could be overwhelmed. With the performance gurantee we were willing to give a try. We have very hard water and were not interested in the salt systems (taste and warning on shrub watering with how much salt would be put in for our hardness) and the reverse osmosis systems are very expensive. We had issues with cloudy glasses (one wash), scale in toilets (needed scraping within two weeks, limeaway and vinegar did not work), and cloudy/scale build up on glass shower doors. Our glasses no longer get cloudy in the dishwasher, the toilets only need cleaning every 4 months or so (3 times last year) and NO scraping! We put vinegar in, soak for several hours, and flush. The glass shower doors have only needed to be cleaned twice in last year and is is very easy with limeaway and sponge versus three treatments with heavy scrubbing before every several weeks.

I have had this product on my well water supply to my home for 14 months now and have really noticed my fixtures, shower doors and laundry detergent usage greatly improved.

Seems to be working.

As far as I know, the HardnessMaster electronic conditioner is working fine. The water feels great.

I installed the HardnessMaster in October 2011 along with silt and carbon filters and a UV unit in the house. There is mostly well water in the outskirts of the Albuquerque area and you can tell how hard the water is by the white stained roofs around the water evaporators on the roofs. I have blood pressure problems, so I didn't want a salt unit in the house. We also have central air conditioning, but I put in 2 medium sized evaporative coolers to see if I could save on electricity this last summer in a couple of windows. I hooked up straight to the well without going through the Hardness Master and I had to clean off the side vents about every week from all the white crud. I have had no problems with water spots in the kitchen or baths. I am very happy with the HardnessMaster.

This Hardness Master Water Conditioner works great - I give the HardnessMaster an A+ rating.
I have a private well - works great for me.

I purchased the HardnessMaster Electronic Water Conditioner due to the fact that my old salt conditioner went out and the cost of the repairs exceeded what I thought it was worth. I also became disheartened with carrying all the salt home and dumping it in the conditioner. I WAS LOOKING FOR AN ALTERNATIVE.
The HardnessMaster Electronic Water Conditioner gave me the alternative. While it might not do exactly the same job as the salt-added conditioner, it does a great job and I no longer have to worry about the expense of the salt and repairs on the the unit. Good job.

I have been using my HardnessMaster unit since 2009. It replaced a salt-type water conditioner. The HardnessMaster does a great job in reducing the lime build-up in the shower.
Also, not purchasing salt is saving me money.

I have hard water buildup on my faucets and shower door. Over a 3 to 4 month period, no more buildup! Thanks for a great product!

I have been very happy with my water softener I do not like the salt systems.
My water is not as hard as in some places, but I noticed a difference within a few days, especially in the shower, I get more lather from the soap.
