Our Kinetico exploded, flooding the floor whilst we were out of the house.
We bought this one as a replacement. It fitted in seamlessly and has run well since.
The water is softer than for the Kinetico (I think we probably had the wrong disk) and it uses more salt as a result. We taste salt in the water when it swaps cylinders. Apart from this it seems pretty much equivalent. The online price was good and delivery excellent.
