I've been using the PACT scale/dispenser combo for a few years and have found it to be as good a system as I could want. It is my understanding the PACT pioneered the concept of an electronic scale providing feedback to a trickler type dispenser which fed back to the scale and so on. Other brands using this system were actually manufactured by PACT and the competitor's label applied until recently. Even so, if your Lyman RCBS Hornady scale or dispenser goes south on you and you have to send it back to the "manufacturer" it will end up being fixed by who? PACT!
