Calcium checker pre order

[globaldesigns]

Question for anyone on these units, or any hanna unit.

Are these still a pain in the butt, same as the normal test kits, but the only difference you don't need to count drops, it gives you the reading? If so, are they really worth it? Also then how much are the renewables that you will have to buy to keep using it?

Thanks for the info, I am really interested, just not sure about if they are worth it.
