As previously stated, I did have to clean hopper with a plastic polish to get primers to stop sticking, ( I used Plexus ) and I had a lot of trouble with the vibration not effectively getting primers to flow properly. Directions stated that I might have to loosen screws holding hopper to base. Many attempts later I finally has to slip a piece of thin plastic under mounting points. I used a tiny hole punch to make hole in plastic then cut plastic squares to fit between hopper and base finally allowing primers to feed properly. I still don't really trust them to be entirely right side up, so I stand and observe primers as they feed. As I get more comfortable with unit I may be able to trust it. It does seem to be operating as intended, but the jury is still out...

This unit doesn't like Winchester primers. However, Josh got me straightened out and now the unit is running great. I don't like how the primer tube angles back toward the machine. It is awkward to use like that as everything is facing away from me.

I was excited to receive this product though, with some trepidation due to reviews I read about poor functionality/reliability. Unfortunately, when I received the product, it had some of the same problems others had reported. I tried to troubleshoot myself using the guides for doing so, to no avail. I contacted DAA and they gave me some additional tips, including spraying the plastic surfaces with silicon spray. After implementing their tips, the device is now working 100% (maybe 1 flipped primer every 1000 rounds, if that). I give it 4 out of 5 stars due to the failure of the product to work right of the box for me; I didn't like that I had to struggle with and tune it. The upside is it now works as designed through about 5,000 9mm rounds with no additional maintenance or tuning necessary. Using S&B SPP.

By for the best primer tube loader I've used. 10000 rounds and one flipped primer. I have retired my Dillon to large primers only. It does take a little longer to load but with a set of four magnets for a total of five tubes I just stay ahead of the game. Cant wait to get one of thes for large primer when it is available.

I ordered the Primer-Pro with accessories just because I hate filling those darn Dillon primer tubes. A little expensive but it's like drinking good beer vs not good beer (no such thing as "bad" beer). Worth it! I don't have a lot of primers right now so I just dumped 4 boxes in the hopper and started playing around with it. Read the directions and wax as instructed. Works as indicated and since it's designed to fill primer tubes I'd have to give it "5 stars" because it fills primer tubes well. I have loaded very few rounds since I got it but have loaded maybe 20 pick-up tubes (and dumped them so I could play with the machine) and I haven't seen an upside down primer yet. Confident enough that I sold my most of old Dillon small primer tubes and applied the funds to pay for the Primer-Pro. If I had to do it again the only thing that I would have done differently was to get it sooner! Alex Ragulsky

Worked flawlessly for the first 15,000 primers or so, then the hammer went out of adjustment. Well worth the investment, but get yourself a very small set of screwdrivers so you can adjust the wire connecting the actuator to the arm. Just like every other tool it will eventually need maintenance.
