Unreliable
I used ph buffer 4 and 7 to calibrate the ph tester. Calibrated it with the 4 first then rinsed off and put it into the 7. Reading was 6 so calibrated it again. After calibrating I put it back into a 4 solution to test accuracy and it read 4.8 making this totally unreliable for taking accurate readings.

Good for ph pen calibration only
It took half a bottle to lower the ph on 5 litre. Good for calibration of ph pen only. I brought some biobizz the other day and it took 1ml to do the same thing.
