Just doing our kitchen and installed this, cant say its a massive noticeable difference, but its clearly doing something, the limescale is going from the kettle is the most obvious

Plumbing was a little bit of a ballache, as we were installing a butler sink at the same time we had a lot of pipework to do, its all lovely and tidy now, but was a mess before from the plumber the builder used
Must say I am a pushfit convert now though, used to dislike them, but reusing the ones the plumber used I had far less hastle than the compression joints I had to make
2 minor issues with the above softner
1) It uses imperial sizing, so I had to go backwards and forwards to imperial and metric as I wanted full bore flexi hoses and those I could only find in imperial, plus I wanted to add full bore 22mm isolator valves then I found the flexis wouldnt bend enough to curve behind the softener, which bring me on to point 2
2) the unit is quite deep so doing the bend at the back was very tricky, I ended up getting some 90 degree 3/4" to 22mm adaptors, but even then its only just got enough room to be pushed back to almost touch the wall and avoid touching the cabinet

OH and if you do it, i was recommended an awesome leak sealer, Fernox ls x. Unfortunately for me I couldn't get the leak to seal from the outside too much mains pressure and it was too close to the wall to get enough to seal the leak, was close but not quite. I did end up taking it off, and used the ls x instead of ptfe, getting the seals on the flexi hoses was tricky. I was sold a pup though but a you tube vid saying just 1/4 turn was enough once "tight", was ******** and when I red the packing it said for 3/4" its a full turn once tight
We are drinking the softened as well. The chilled goes through the fridge filter, the stuff for the kettle from the softened tap. I could pretty easily switch the cold kitchen tap to unsoftned as I already took a spur off before the softener for the outside tap.
