Review on 📏 Smart Weigh 50g x 0.001g Digital Milligram Scale Set - High Precision, Includes Tweezers, Calibration Weights, Three Weighing Pans, and Case by Iris Swatson

This will be the first and last scale I will buy from this manufacturer. I weigh what came out about 0.56 grams of gold, then store it and take it out after about 4 days to demonstrate how the scale works. Then the scale started acting very strangely, like there was something on it, but there was nothing. I continued to calibrate, following the instructions carefully, and it seemed to continue to read 'pass', but as soon as I removed one of the 20 gram calibration weights it continued to measure the remaining 10 to 12 grams and I replaced the batteries. with a fresh AAA set and about 3 more calibrations but still no luck, hopefully it's just a bad block but now be careful with my next scale.
