Very good color contrast By Chris on 2/13/2014

I've used the salifert ph kit for over a decade. The problem with it for me is the color contrasts aren't enough. Due to being color blind I have a difficult time telling the difference of values. The Elos kit provides a better contrast for me.

I have used API in the past but these tests are so much easier to read.
Great test kits! By Christopher Kosak on 10/7/2010

I only use ELOS kits after switching from the API kits. I believe ELOS has the best test kits and they are top notch quality. The PH kit is very easy to use and im sure you will not have a hard time conducting this test kit.
