In March of this year, I purchased the complete set of refills.
When doing the PH test, it never showed any color that was recognizable. I finally used some leftover reagent from last year --- no problem!!
That's when it dawned on me - I had to double the drops in order to get a correct reading.
Apparently the r-0014 is a diluted form of the r-004.
Since I mixed and matched bottles of the new refills with some that I had left from last year, I don't know if I can trust any other results from my tests.
Pretty disappointed with this purchase. Wasted $40.00
I'll slowly replace my refills individually as I have done before, as money become available.
