Bests & Worsts Reviews from Amazon

I had earlier posted a review on this saying it doesnt seem to do anything. I am changing that review now, but for some reason amazon wont let me change the number of starts I rated this at ... I now give this 4 STARS I had earlier posted the review that this doesnt seem to be doing anything, but I left it on. Interestingly - while it took its time - this thing does seem to be doing exactlt what it says it will do - namely - making the hardness in water "non-sticky". My shower heads look quite a bit cleaner, and yes we are noticing small while precipitate in the water, showing that the long deposited white 'scaling' on boiler and pipes is actually coming off. This seems to also have had a very positive effect on the dish washer. I dont get the whole scaling on glass anymore. So - if you have tested your water - and its hardness is in the range for this device (mine qualifies) - I will now very strongly recommend this to you. Its a peach to install and setup, and provided you have the patience to wait for its effects - which can take a few months to show up - this is great.
