This is a no-frills scale that (without tapping) weighs amazingly, without first turning immediately. However, I would estimate the measurement accuracy despite the 100 grams subdivisions to about 0.3 KG, that "actual weight +/- 150 grams" = "displayed weight". As a test I took after the first weighing even a few items in the hand and the scale showed changes 100-200 grams, no other weight on.
Conclusion: a simple and very quick scale for very reasonable price. For people, for 100 grams while weighing not play a major role, strong buy recommendation!
