Seems to be a great meter, better than previous buys.
I've bought three different inexpensive PH meters, they all quit working fairly quickly or never seemed to work correctly. This one is different. It was troublesome at first, the first few uses I had to calibrate it several times to get it close to right then would have to do it again the next time. But after a couple of days of daily use it settled down and now it reads the calibration solution correctly every time and gives me consistent sensible readings. Just don't get discouraged if it's not accurate at first. It seems to need time to "break in". Another thing to watch with all meters like this is battery state. If the batteries are even a little weak readings will be inconsitent. I don't need double digit precision so if it's within .1 that's close enough but I have no doubt if you did the full three solution calibration it would deliver reliable double digit accuracy.

Just what I Needed
Bought this when setting up a new tank and the strips wouldn't read the PH correctly. Well one test with this and it told me my PH was way up (strips only go to 8.5 and I was well over 9) Easy to use and as much as I can tell is super accurate. Still use the strips but this is something I can do every day to see if my fixes are working for the PH and not test for everything. Would buy again with no remorse.

Missing parts and not clear instructions
I ordered this item for winemaking testing. Product came with a nice case and an instructions pamphlet and calibration solutions. My order was missing one of the calibration solutions calibration solution, pH6.86. Out of the box the unit could not provide a reading for distilled water pH using the instructions provided. The calibration instructions are not entirely accurate or are missing information as it does not explain if you need to use all of the 3 different solutions to calibrate the unit, in what order, the flashing display is not the same as the instructions. Overall, I can not say how well it worked because it did not work.

Finicky and not sure if it’s accurate
Easy to use. Seems accurate. I will update as necessary.Update: After about 3 months of use I’m not sure how accurate it is. I have another TDS stick and this always reads significantly lower. Also the numbers and readout frequently go unreadable when in use and I have tap the stick for it to read clearly again. It’s either this stock or my other one that’s inaccurate but I suspect it’s this one.

does not come calibrated. a pain to calibrate. not worth the trouble.

Ph tester
Value for the money. Good quality and ease of use.

Works Great
I just got a cool new gadget - a pH tester! It's this nifty little device that's super easy to use, with clear instructions. The wait for an accurate reading adds a bit of suspense (30 seconds!), but that just makes a good result even more rewarding. Plus, it's compact and affordable, which is always a win. Now I can keep my plants happy with perfectly balanced water!

Will not calibrate.
I liked the price, but this PH meter is bad. It will not calibrate at all. It never stabilizes. If it will not calibrate and it never stabilizes, then you can not get an accurate reading and that means I can not keep the PH level in my hydroponic systems right.
