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.
very happy
Purchased this to reduce scale problems in the house. It woks very well. If something changes I'll repost
3 month review
We have very hard water from a well. Thank goodness it's the only real issue we have with our well water. I installed this on my cold pipe going into my hot water tank as per the instructions. It is definitely doing something to the scale but it's not making it go away. Instead, we are getting a lot of this white powdery stuff appearing in our drains and aerators. I called the company and they explained that is what its supposed to do. Once it's done descaling the system it should stop. I gave it 4 stars and will raise to 5 when it stops.
Still shows as hard water
I live in a hard water area and I will say that this device does keep the scale from sticking to things. It however doesn't lower the number of solids in my water. My TDS meter still shows the same number.

Worked perfectly
I don't live in an area that has ridiculously hard water. I believe we have a hardness of 125 ppm. This is why it worked so perfectly. Hard water is merely a nuisance and it's not at a level where I need a water softener plus I don't want to add sodium to my water. I simply want the annoying staining to stop. After 2 weeks of being installed, it did its magic. The hard scale deposits went away and the ones that were left over were easily wiped away. So glad I get to keep the healthy calcium in my water and not have the problems. Well worth the money. I had previously tried a similar device that used magnets, It did nothing to help with the problems we had.
Happy with my purchase
I didn't want to use a water softener so I decided to give this a try. Very happy with my purchase so far
6 months in use
I decided to wait to put this review up so I could see if it actually worked before I threw my 2 cents in. I have a 2 story home with a water filter. Unfortunately, the filter didn't do anything about the hard water issues I have After 6 months I can say I'm very happy with the results. I'm not sure why, but I do need to change my water filters a little more frequently since installing it. Apparently, these devices must increase the filter's ability to grab the particles out of the water.. This was a pleasant surprise since I was only expecting it to help with the scale build-up all over my home's plumbing system, which I'm happy to report that it did.

First time I've tried this
Ive had this installed about a week and so far it appears to be doing its thing. I have noticed that scale is present in some areas but it does wipe away easily.
Update on my HydroFLOW
I hope this finds all of you well! Just thought I'd give an update on my Hydroflow. Last December (2020) was the last time I needed to clean the coil on my boiler. I did use a different technician the last 2 times who uses an all natural product and perhaps that has made some difference. However, I think the real impact has come from the Hydroflow which over the course of several years cleaned out the pipes of accumulated scale. They must have been terrible! I have much less scale, if any which comes out of the faucets. I hope this continues! Nancy
Did not soften my water
I was expecting to see my water hardness go down. It didn't. I did see scale disappear from my fixtures but my TDS meter still shows the same hardness. Apparently, this does remove the scale but doesn't soften my water.
