I have that exact balance, but i bought mine on Amazon. I verified its accuracy with Mettler Toledo 11123059 CarePac Customized 3rd Weight OIML, Class E2 100 g Weight and it was good. If 1 milligram is good enough resolution for you, then go for it. If you are measuring things that are 5mg in weight, then you need a different scale, b/c 1mg will be a 20% error with such small weights.
What i found is that reading varies slightly depending on there i place the weight. In center of the plate it was spot on, at the edges it was +/- 8mg with 100g weight.
The comment above about 3dp is wrong. With 100g load it is 6dp.It reads up to 200g with 1mg resolution, so something like 127.134.
It works better plugged in than on batteries. With not a brand new battery mine failed to completely load, even though display lit up.
