I've had the same dispenser for a couple years, love it! A bit of a hassle to clean at first, but after ya get used to it, it's not an issue. I do as Mac does with his, open the chute in the back, let it empty most of the hopper, close the chute, rotate the feeder tube so the slot it down, lift and tip the scale to each side so all the powder comes out of the feed tube, open the chute to let the last bit of powder out, clean up with the little brush if needed, you're done. It takes longer to explain it that to do it!!!
The scale is slower than the RCBS combo, but doesn't cost as much either, $200 compared to $260 minimum for the RCBS, they're both made in China. To speed dispensing, I used a dipper to fill the pan about 90% full, then let the scale top it off. While it's running, I seat a bullet in the last charged case.
