They seem to be junk if you ask me. I really do not understand the mixed reviews, they either work 9r they dont, and so far I have yet to find a reliable one. Using distilled water and my meter want calibrate the 9.18 solution. I put it in the 6.86 solution first, wait a bit and hold cal, it flashes 6.86, ok good. Take it out, clean with distilled water, stick it in the 4.0 solution, wait a bit and then hit cal again, it flashes 4.0, ok this is good. Clean the meter once again, stick it in 9.18 solution, give it a bit, hit cal, and it flashes 6.86, wtf. Have been doing this for like an hour. Idk I'm about to just buy ph strips and a tds meter. I found the tds part to be pretty accurate, the ph meter part seems to be a joke.
