I have had this loader I got from amazon for about 3 months. I have loaded at least 3,000 rounds of 45 acp both large and small primmer cases on it. Any problem I have had has been directly my fault. If you keep this press clean, you will have no problems. I can do about 300 rounds per hour using it. I usually weigh about every 20th case just to check powder throws and they are within .05 gr every time (thats using Hodgdon Universal powder).Here are my tips:1. When the primer tray runs out, fill it up. The weight of the primers in the feed tube push the primer into seating position. Keep it full and have zero primer problems.2. I put a baffle in my powder hopper and it evened out the consistency from when it is plum full to almost empty. If you don't do this try and keep the powder at about the same level. Maybe fill it up after every hundred rounds or so.3. Keep a can of "canned air" handy to blow any powder that hops out of the case when indexing.4. Run the press as smoothly as you can. Always go full complete movements. Run the handle and feel each stage and the press works.4. THE MOST IMPORTANT TIP. Once you get it all put together spend an hr or two figuring out exactly how it operates and functions. Then do fine adjustments on anything you see that needs it and slowly work into it. If you jump into it two fast and don't know what you are doing, you are bound to fail.This is a great press for the money if you take your time setting it up and getting it ready. Don't buy the negative ratings. If you have any mechanical aptitude you can run this press around 300 rnd per hr without problems. If you want a blue loader then buy a blue one. If you want a loader that will do 300 rnd per hr and not break the bank buy this one.
