I bought one and used it once and went back to my 10-10. It's still sitting on the bench so maybe I should try it again. It just seemed too slow. I can move a lot faster using one of my powder measures and a trickler.

Personally, speed of loading is not a consideration. I just do NOT trust electronics. I use a single stage press, RCBS Rockchucker. Had it since the 70's. I have a uniflow powder charger. I set it to throw less than the amount I need and trickle every single charge into my scale. It is just me and I don't load the volume of many here.
