Great tool and total recommendation, no installation manual included, but the video from Saul is even better and understandable. It takes a little time to set it up correctly, but after that everything runs smoothly, and even after 3000 cartridges it is still without problems.
I am really satisfied in using the DAA Mini Case Feeder for my Dillon 550, without taking my hand off the roller handle every time while loading.
I suggest everybody to get a second or third case feeder tube, because 150 cartridges are now loaded very quickly.
The only thing that bothered a little at the beginning was the steel pin to hold the activator in position. After a reloading season, when take the tool head down to empty the remaining powder of the powder hopper, you have to loosen this pin every time. But after a few times of practice, its getting very quick.
