The Chargemaster series of auto dispensers have been on my bench for quite a few years now and have been solid. The 0/50/100 gram calibration is kind of a joke given most powder chargers are less than 5 grams (77 grains).....but that's the way RCBS configured the auto-calibration. I do have a set of NIST traceable lab weights that I use to verify the scale in the 1 to 5 gram range before starting and periodically during. Also, I plug the units into a clean power supply.
