I love the look of the 3-in-1 pH meter but that's about it. The first thing that came to mind was that the powdered pH base that comes with the device doesn't actually dissolve and it made me feel like it wasn't going to give me my base pH levels to calibrate the device. The second observation I had was that after calibrating the unit with my own general hydroponic stock solutions, it was still 1.4-1.6 above actual pH. I don't like capital letters in my sentences.
