Rated 3.0 out of 5.0 by Worth keeping at one-third off price Bottom line: I've had this product installed for 6 weeks. It is on the pipe from my private well before the pressure tank. It has met my minimum expectations for the price I paid. At one-third off I do not feel compelled to return it. At full price I would have likely expected more. Details… Water source: A private well, probably drilled in the 1960's, 46' deep to submerged pump, approx. 125' from salt water tides. Pump and drop pipe replaced less than 6 months ago. Whole house filter system (see picture) installed less than one year ago. Water test performed years ago found: hydrogen sulfide (which causes the water to smell like 'rotten eggs') and salt water intrusion. My own observations: during the summer the first filter (on the right in the picture) typically turns black within 2 weeks of being replaced; that has not happened with this device installed. The smell is worse in summer than winter. Expectations: 1) minimum requirement to not return product: more lather and better rinse while taking a shower - passed; 2) want: less black residue in the toilet between cleanings - it's not black but is now rust colored; 3) nice to have: fewer water stains on chrome fixtures - seems better; 4) doubtful: reduced 'rotten egg' smell - not a chance this product was going to help, only solution I know of is to introduce chlorine. Caveats: My water quality seems to vary by seasons. It may even vary by the tides. Since I have not yet passed the 90 day suggested validation period I'm hoping that the rust color instead of black may be that my pipes are clearing out. Although I observe that the second filter is now turning rust color when it didn't used to. Ultimately, I cannot be sure that this device is the only reason I've seen changes. The alternative is to run a thorough test that would require a full year with the device on and a full year with it off. That's more trouble than I'm willing to go through. So I'm going to assume the changes are real and are a result of connecting this device. Footnote: I asked a water quality engineer if she thought it'd work. She was not aware of the product but indicated that she believed that if the wire wrapping magnetizes the iron particles in the water something would change. Tip: if you choose to install one, I found that during pipe wrapping it was helpful to use a Sharpie to mark every 5th wrap. That made it easier to double check my count. Based on my research from links I've followed from here and independently, I may be fooling myself that this device helps. But I will choose to accept that without regret. As we say on the motorcyclist forums: YMMV. Your Mileage May Vary. August 20, 2015
Rated 5.0 out of 5.0 by What a difference! I have been waiting on this unit to g on sale for 6 months. I got it delivered within two days and my next day off I installed it. I was skeptical that this magic box would work but to my surprise my water was noticeably different as soon as I plugged the Scale Blaster in. There are no more deposits on the dishes in the dishwasher, my hair and skin feel softer and slowly but surely any scale in the house is disappearing. The unit is simple to install, maintenance free, and I don't have to buy and or store salt. Why would anyone buy a traditional water softer with this product out? October 13, 2015
Rated 5.0 out of 5.0 by Low cost to operate and it works We purchased the scale blaster when it was the "deal of the day" ($270) at Home Depot a few weeks ago. We didn't have particularly "hard water" (higher concentrations of Ca & Mg) but it does appear to work. The water tastes better and the sinks & faucets appear to be cleaner. Don't expect immediate results. The science takes a little time to work on the deposits in pipes, fixtures, etc. Our goal is to extend the life of our water heater, dish washer, and washing machine which should accumulate fever water deposits over time.

Rated 5.0 out of 5.0 by Great Product! I had the SB-75 installed in a house we were renting in CA. After initial installation, it wasn't immediately apparent it was really doing anything (they say give it 90 days), though I could tell hardwater spots weren't as prominent around the sink and washing the car (I installed it on the water main). But when it stopped working (about after a year), we could tell immediately because the water went from "soft" to hard. You could really tell when washing hands or taking a shower. We just bought a house in Phoenix and the first thing my wife asked was, "When are you installing the Scaleblaster?" LOL Which is funny, because she was the one not sold on it in the beginning. But this time, I went with the SB-175 so I could again install it on the main without having to drill holes through the foundation to run the 18-gauge wires. I'm also tapping into the power that's running the swimming pool equipment. I'll post pics when it's completed. However, the internal SB-75 is easy to install. Btw, the folks at Scaleblaster were great to deal with when it stopped working. They paid shipping both ways with a 2 day turn around. Though I had to go almost a week without. Do your pipes a favor, get this device. I'll likely stop using the water softener once this takes over, saving me the cost of salt and wasted water flushing the softener February 22, 2015
Rated 4.0 out of 5.0 by So far, so good I don't know the science behind this, but my wife has been on me for years to install a water softener. My in-laws had this installed in their house, so when I saw it on sale at Home Depot, I thought "why not". If it doesn't work I'd blame the precedent setting in-laws. Well it's been in for two weeks, and we all think the water is softer. The Brita filter doesn't have dried water droplets on it anymore.....soap lathers easier....and wife seems happier (with the water). I know it's only been a few weeks, but we'll see. We did a major CLR cleaning on all the fixtures, so we should know if this continues to work the way we think it is. Easy to install. One suggestion to make the installation more manageable....wrap the wire around a short piece of pipe before you install, and use that to feed the water supply pipe you are coiling (think kite string on a spool) March 25, 2014
Rated 4.0 out of 5.0 by Great Product! You can see it working! We love this scaleblaster, our only issues so far is getting through the initial cleanup of our pipes as it is dumping out tons of minerals. We did email the manufacturer and they told us this will clear up as the product need approximately 90 days to show its true potential. I recommend not running your heat dry in dishwasher until you are past this stage as it bakes on the minerals... Another thing I wanted to make homeowners aware of is that it is somewhat difficult to install if you follow their recommended directions. You should have the wires on 12 inches of straight pipe and preferably on the main water line into the home as a soft water loop may leave out your kitchen sink. We had a plumber put a loop on our main shutoff so that we attained that and then we did the rest ourselves, very easy with two people, one to hold wires and one to wrap. Then you just plug in.

Rated 4.0 out of 5.0 by Salt Free Easy to Install Unit removes scale from hard city water without having to use a salt system. No salt and no maintenance. Enclosed wound coil in larger PVC pipe for appearance and protection of coil mounted outdoors. Excellent value at sale prices. November 3, 2015
Rated 5.0 out of 5.0 by What Calcium? I bought this for the primary reason that my water had a severe calcium build up which the water comes from the township. 2 Weeks after the install I noticed the sink in the kitchen had significantly less calcium on the walls. Now about 2 months after the install I see no calcium buildup. So I am quite pleased that this product does what I bought it for. One Item of note is you need to read the instructions carefully when installing as you wrap the wire differently depending on the type of water pipe. August 18, 2015
