Tested with Lyman scale weight set and was right on the money at all weights. Dropped a 1/4" square piece of paper on the scale and it was .1 grain as verified by an rcbs 1010 and lee scale. Tested many times over a week and always was on the money.
The plastic cover is too small to use with the powder pan in place, so I just use a clear plastic bowl to cover it.
Pros: Repeatible Accurate Small Footprint
Cons: No Cover to block air currents
