Bests & Worsts Reviews from Amazon

Would not recommend. Scale does not give repeatable readings even after calibration. Was using it on a stable granite surface, no drafts or vibrations. Can load a 10 g cal weight (read approx 10 g) then add the 2nd 10 g cal weight (reads approx 20 g +/- 1%). Take off the 2nd weight and 1st weight reads 9.5 g (?!). Add the 2nd weight back on reads (roughly 18 g). Massive drift when weighing 100-200 mg samples. Constantly need to tare (ie between every single sample).
