10 years ago Salifert was the only one that looks the same as it does now. I didn't hear about Elos until 2006 ish when it became the new "best" test kit. Hanna has been using the colorimeters for ages, but the Checkers are still relatively new. I don't think the Checkers have been looked at that closely.
