I skimped on my ph meter and bought the Milwaukee one. I WOULD NEVER SKIMP AGAIN on such an important piece of a grow. These things are ticking time bombs.
I have had this PH meter for a year now, and haven't had an issue, calibrate it before every use and bought new calibration solution, 3 part, but thats it...This post was meant for peeps who can't afford the pricier pens, turned out well for me, also helps to have a background in lab. I work in the Waste Water Industry..PH, CL2, TDS, Microbes, all part of my job. If you keep this pen clean, stored correctly, and calibrated often, it works.
