I am also wondering for the same reasons. So I will be following waiting for someone who has one. Although from some reviews I have read, not too good. Something about extra steps and perfect RO water needed for settting to 0. I have a Hanna Alk and Phos that are real easy to get to set at 0, you just push a button. But I really don't understand would perfer an actual user.

i have now used my hanna ca checker and it's pretty simple to me. yes you do need 0 tds ro water for best results but it has been a lot easier and more reliable than having to decipher a shade of a color on the rainbow richter scale. lol
