I don't see where this is mentioned on the site yet, so here's the warning...
I ordered my Hanna Magnesium Checker before they came out. As it turns out there have been issues with this Magnesium Checker. The common complaint has been that the test results are too high. (I have had the same issue.) Hanna now says that a reagent in the test kit degrades much more quickly that anyone there had envisioned.
Hanna will send new improved reagents to users if they sign up on the site and provide serial number and purchase info on their Checker.
Here's Mr. Saltwater on the subject:
