I've only had two problems with mine, and only one was the press. My first problem was the spent primers were not dropping free, jamming the press when I tried to index it. After trying everything I could think of, I finally realized that they were sticking on the decapping pin and pulling back into the case on the downstroke. I chucked it up in a drill and put a slight taper on it and rounded the corners slightly. That never happened again. Then, I noticed that sometimes the shellplate would not index quite far enough on the down stroke, causing me to miss seating the primer if I wasn't paying attention. I thought I would need a new spider gear because after checking things out, it happened every fifth stroke, but after calling hornady, the tech said that it can usually be adjusted out with the pauls, and advised me to try that and call back if needed. I was skeptical, but tried it anyway and it works great. My press seats the primers just slightly below flush, every time. It does not take an excessive amount of force to seat them. If it does, something is wrong, even if they go in all the way. All I have used are winchester primers in mixed 9mm and .45acp brass. I did learn that the timing adjustment is easier than I thought if you know what to listen for. When you are adjusting it, move the handle very slowly and listen to the clicks as it indexes. If you hear two clicks on the up or down stroke, your timing is off. Adjust the timing until the clicks run together as one, and the press should run smooth. If you can't get it like that, you probably have a bad spider gear or pauls. I hope this helps someone, and know it's not going to fix all the issues on the thread, but I just wanted to relay what I had issues with and the fixes that worked for me.
