Much better results than color chart tests
Works great and much easier than the color chart tests. The liquid reagent though is very sticky and challenging to clean up if you spill it. I started pouring it into a glass before using the syringe. Not easy to use packaging in that part.

Good Magnesium Checker
This one was a little more involved than the alk, PO4 and NO3 checkers but still easy enough to use and great to have a number instead of guessing on standard tests. Helps to gauge when to add more Mg to the system.

Save your money, many cheaper, easier to use tests kits exist from other manufacturers.
Have the Hanna alkalinity tester and it works like a charm everytime. The Magnesium tester is a piece of junk. The process to test is way to involved, any extremely slight miscalculation of any of the three samples skews the results greatly. Also, the corvette supplied do not securely attach to the syringes supplied so it is fairly impossible to even get an accurate reading on the doses. Save your money, by a different brand if test kit for Magnesium.

Actually works very well!
Love being able to take 5 minutes out of my day to do the test. One tip, set a 30 second timer or the last step and shake vigorously. Then pop into the egg and hold the button till the 3 min counter starts. After 1 min is left open the egg and pull the glass vial out and tilt back n forth to dislodge any bubbles on the glass then pop it back in before the timer ends. That way you'll get a very very close reading if not a perfect reading. This is the new revision and works extremely well..
