Steady readings.
Was actually surprised how well this works. It's cost effective. Easy to clean. Easy to calibrate and use. Very durable. Lasting me a while. Doesn't break.

Inexpensive, but good PH meter.
This is the second of these PH meters I've purchased. There are a number of negative reviews, so I was a little concerned but went ahead and order one. The first meter calibrated easily and (apparently) accurately. I used the three point calibration, then tested my fish tanks and compared the reading to the drop type ph test kit I had been using. It was spot on as close as I could tell with the test kit. I used the meter for a week, every day on several tanks as I changed the ph. It tracked these changes as I would have expected it to.It worked very well for me so I ordered a second PH meter. (I have fish tanks in two locations.) I then used these two meters side by side. They vary from each other by 0.10 points. The second meter did not calibrate as easily as the first, and the calibration was off slightly. I will try recalibrating, but it's as accurate as I need now. I'm very satisficed with them and would recommend.

Calibration is weird
Somewhat hard to calibrate, but it feels like decent quality. Easy to use and quick to use after calibration

Don't Waste your Money, Less than 3 months Old and Broken
Worked for a month and then PH started to be off. Tried to recalibrate following the instructions the same way I did when product arrived and it will not recalibrate. I have tried several times using all 3 methods of calibration with vivosun powder and all I get is an Err code when trying to calibrate. Chinese crap with Vivosun name slapped on it. Past the return window, so I guess it can be a paper weight.

Good When Calibrated, but then…
Freshly calibrated, this meter works fairly accurately (within .2-.4 of other sources I trust. I mean, really, for well under $10, it’s bargain! HOWEVER…There is a reason the instructions say to calibrate daily, before each use. After using it about 3 times, in various solutions I found it to be 1.5 units off! But once recalibrated, the circus was back in town and it once again gave accurate readings. But I’m just not willing to go through the calibration hassle before using each time. I even tried a trick a buddy should me where you stuff a tiny bit of cotton, torn off of a ball, way in the back of the lid and very slightly moisten it (6-8 drops?) with distilled water; this is suppose to keep the glass reading probe very slightly moist and therefore help keep it better calibrated.If you’re after accurate readings, and are on a budget, and are willing to pay for extra calibration powder packets, and do the calibrating before every use, this meter might work for you.I returned it and went back to my Biopharm droplet test kit—pretty accurate and reliable (General Hydroponics also makes a good droplet test kit, but not with the .5 increments that the Biopharm reads at).
