From what I have read ATI (German) appears to be the best. Triton North America had some early user errors, Marin Lab (Poland) is OK and Coralvue (US) is not reliable.
I am really not sure that you can even compare hobby grade test kits, that are wrought with human error to lab grade ICP testing done by a knowledgeable lab technician.
From my experience with hobby grade test kits they tend to be relatively consistent if we take out the human error factor.
I just wanted to know how my readings compared to the lab testing. I also wanted to confirm that there were no unwanted substance (heavy metals etc.) that cannot be tested for.
