I got me a set of these scales a couple of months ago, and was generally impressed. However, they have a flaw: they appear to measure in hundredths of a gram and then convert to grains. This means that certain values in tenths of a grain do not appear (1.3, 55.5 for example ). This is more annoying than life-threatening, and means that the accuracy is in fact 0.15 grains with accompanying rounding errors. Bah.
