I have the older style RCBS Powder Pro digital scale and the Prowder Pro dispencer. It was not working right either so two years agoI sent them to Pact Inc the company who makes them RCBS. Not only did they fix the problem but they also upgraded it so it flows twice as fast and it can dispence up to 150 grains instead of just 100. From my understanding the new ChargeMaster Combo it just as fast as my upgraded system and it goes upto 300 grains. Its suppose to be a better until, time will tell I guess. I sure do like myupgraded system no problems so far.
