Having used the graviTea now constantly for 6 days, I am happy to report that there is virtually no scale in my utilTea, nor on the glass teaware that I use all the time. I think I can attest it does cut dramatically back on scale.
I have a well, so cannot comment on the chlorine eliminating abiliTea, nor am I prepared to say that it improves taste since I have had great TeaDays almost everyday before and after using.
But I will save a $fortune$ on vinegar
and time cleaning/removing scale
which is a chore I never did care for.
