really hard water
Purchased one of these things a month ago. I have really hard water and got sick of using a water softner. Decided to try this out and it works great. No scale buildup in the usual places. Very nice and contrary to what others say it was worth the price to not have to deal with salt and the softner.

Works very well
Bought the Pearl Plus about 6 months ago. I was having problems with scale because I have very hard water and got sick and tired of buying salt (and drinking salt water) so I gave the Pearl Plus a try. It was a gamble but I'm very happy with how it is preventing scale from building up. I'd rather drink a glass of water with natural calcium vs salt water.

Surprisingly Good
Pearl Plus was installed about two months ago and the results have been amazing. Most obvious is on the through-the-door ice and water dispenser on our fridge. Prior to the Pearl Plus there was lots of scale build-up. I cleaned the drip tray, but some scale remained. Somehow, the water that inevitably collects on the drip tray has since removed the remaining scale. Unexpected, but delighted.
Made it easier to clean
This product made the hard water easy to clean up. It didn't lower my hardness levels.

HydroFlow s38
Our house is a new copper construction with water flowing through the system for about two weeks prior to installing the HydroFlow, the hardness is 250 ppm, alkalinity 240 ppm, and pH 7. After a day with the HydroFlow, the dryness of skin and itchiness after a shower has been reduced and hair seems fluffier.

5 stars
I'm a new home owner and I didn't want a water softener. Here is what I experienced. I contacted the company to help with the installation. It was incredibly easy to install. Installation= 5 stars (my 8 year old could do it). I have seen no scale anywhere in my plumbing system= Effectiveness= 5 stars. There is no maintenance, and I didn't see my electric bill increase at all. Maintenance = 5 stars. The only downside is this product is it is a little expensive. Cost= 4 stars (you get what you pay for) As you can see this product has earned 5 stars in my opinion.

Finally! got my hands on a Pearl Plus. It's installed and running! and I'm sure it will perform as nicely as my s38 unit does. If it doesn't I'll come back and change my review
Very Pleased
I live in Utah and I have really hard water. I've always wanted to try one of these out and finally got the courage to give it a go. I'm so glad I did. I don't see any signs of scale and my water isn't slimy from the salt. Works better than I thought it would.,
Installed this 7 months ago and I have not had a scale issue anywhere. Very pleased with the results.
Worked great
I have very hard water and this little device stopped all the problems that scale was causing. I would give 5 stars but I gave it 4 because of price.
