Review on Hanna Marine Magnesium Checker® HI783 by Zach Flame

This has to be Hannah's worst test ever. I have almost all of the Hannah checkers and they all work like a breeze. However, this never shows anything below 1800. No matter how often I test. All of my other parameters read fine on my other controllers, but this one just doesn't give me any real readings. Not to mention the shots they give you don't fit, the tip always falls off no matter how hard you try. I think I only got ONE accurate result and even then I felt I couldn't rely on it because I felt like just trying to pull the reagents wasn't accurate. Stay away from this product until Hanna improves it. Because BOY is terrible!
