Great price and works very well once calibrated.
Arrived with the plastic box it stores in all busted to crud. Luckily the ph meter itself was fine. But needed immediate calibration. Was reading 6.1 on a ph 7.0 buffer solution. Luckily i have a better Oakton meter that just needed batteries and is very accurate. But this one works almost as good as either of my Hanna ph pens. The standard ph pen and the ph ep pen which both have broken electrodes which are ridiculously expensive to replace. So for the price it is a great deal. Once calibrated it maybe has a +/-.1 to .2 accuracy. Not bad for under $15. Came with the 3 calibration solution powders. I prefer liquid calibration solutions but well worth the money.

Worth it
Accurate enough, no need to spend a fortune. I know these get a bad rep but I had no pH issues while using this. Just calibrate following the instructions and make sure you have distilled water handy to wash it after every use. Worked perfectly through my entire grow.

You need disteeled water to calibrate
Works great

Waste of money
The batteries were leaking. Threw it out.

Don’t buy any of these.
There are several brands all selling the same garbage unit. They don’t properly calibrate, so they are absolutely useless as a measurement device. This one (my third of this bad design sold under several different brand names) is the worst. I can calibrate it, then watch as it literally drifts from calibration in a matter of seconds. The numbers just keep going up while it sits in test solution. Is my pH 4.0? Or is it 4.1? Can I get 4.3? Wow! My test solution is now somehow 4.5! And still rising!
