Anyone tried this?

It is quite pricey, has anyone tried it? Guess I could sell some Hanna testers to offset cost but wondering about accuracy, etc

a couple tests work great - a couple important ones almost never work (including the ability to get a Ca & Mg measurement).

Don't waste your money.

Or - if you just want be sure - I'll sell you one for half price.
