Pros and cons.

The pH meter is good and easy to use but it's initial calibration is tricky. One has to be careful with the pH powder provided with the meter. I have used deionized water to calibrate. But deionized water is available only in 5 litre plastic can which costs about 200-300 Rs. Without correct calibration, the meter will give you a wrong reading. One can search You Tube for calibration tutorial.
