Review on 🟡 Alysontech Digital pH Meter: High-Precision Pocket Water Quality Tester (Yellow) by Amanda Rodriguez

***Update*** Purchased new calibration packages elsewhere. Same problems, so this suggests that the device itself is junk. Issues 1) Unable to calibrate against provided solutions. I can't tell if the calibration bags are mislabeled or if the meter isn't working. - 6.68 calibrated to 4.0 - 9.18 calibrated to 6.86 - 4.0 calibrated to 0.0 (which I know is incorrect). And then the meter started acting weird until I took out the battery to reset it. 2) The instructions are vague, poorly written, and don't give the correct steps to calibrate. Search the net and you will find more detailed instructions. All in all it seems like a waste of $15 on another Chinese crap that doesn't work. I've ordered some calibration packs to see if this is the problem and if so I'll update them, but for now it looks like garbage to me. 4) The device does not match the picture. Mine isn't yellow, it's white. Nothing bad, but makes you wonder what the company is doing.
