It is good product and value for money. It provides accurate readings.

Calibration is a big headache. Using the 6.86 buffer powder is also not giving proper readings. Getting a reading of 7.7 after calibration and when checked with the litmus paper shows safe reading between 6-7.

changing my review after calibrating it.. works fine now.. still very cheap pen, almost use and throw.. if you're on a budget, get this.. but if you can afford, get a better one.. spend some money, for such meters, quality > cheap quality is less expensive in the long run

Good

The product seems defective as it only works when I put my finger in the off/on button. Please contact me for a change of device.

SMALL VARIATIONS

I was skeptical at first seeing its low reviews but still chose to give it a shot. It DOES NOT WORK! Don’t waste your money on this. Try to find something in the local market because not much options available online. Plus you can return it in a shop.

Very nice accuracy
