In total i have fully processed #815 223 brass with it since buying it a few weeks ago. A little early for a review but I figured a early review can always be followed up later so here is where I am right now as far as my first uses and impressiins . On a negative note I did dull the deburring tool already it started about 750 cases in and by the time i was done it was done. On a good note the chamfer tool remained sharp thus far however it was warped from the beginning and made it harder to lign up a case. The cutter is still fairly sharp though but I dont trust it after experiencing the quality of the bits that came with it. Anyhow Since I already had a Lyman hand tool with good bits i went ahead and changed them out with the exception of the Cutter. If I had any suggestions to this point I would say go ahead and grab different bits right off the bat when or if you get one of these. It seems the quality control in the heat treating process in China is still lacking and they seemed to have invested their time and money into the prep ceter itself. The Fit and finish of the Trimmer/Prep Center itself seems pretty good. Solid construction from appearance. Casing is all metal with the exception of the back panel. The tool head face plate is solid cast aluminum. This thing is not light either. Not like some Typical chinese import tool you might find at harbor freight for $15. Though the jury is still out on how it will hold up over time, my first impressions is that it was a perfect fit for my needs. Price was right for what appears to be a great tool and value for me is where i sum up my description of the Frankford Arsenal Trimmer/Prep Center. Plus it is pretty fast at removing military crimps using the Lyman primer pocket reamer bit. As i posted in my first impressions a few weeks back setup was simple. Adjusting the Trimmer to a different length is easy too. my advice is to go ahead and check out a couple YouTube videos on it it's pretty simple pretty straightforward there's nothing hard about it and you will see for yourself if you happen to get one how easy they really are set up. Also I think the tool fits certain people better than it does other people. If you rarely trim brass and in smaller quantities and you have all the time in the world then there is nothing wrong with one of the little Lee cutters chucked in a drill. I have a few they work fine but they are just slow and a little finicky for my needs. Lett's be honest I hate and I mean loathe prepping large quantities of rifle brass for plinking purposes. I don't mind hand prepping cases at all in my precision rifle because I don't shoot tons of rounds and taking my time to prep up 50 or 100 cases is not that time consuming. Plus i can be more precise with them which is the goal.
