Sounds like a YOU issue, and not a bluelab issue?You got lucky their "pens" suck my grow shop doesn't even sell them anymore they sell ones that you can swap the tip out and it is on the spot out of the box for pH & EC/PPMx700. I just use the bluelab truncheon and drops.. Pens are too high maintenance for $50 I can have enough pH dropper kits for a year and its never not accurate or batteries died or gotta calibrate and buy solutions n shit.
