I just used it and I loved it, trimmed the cases down nice, left a great chamfer on them, and I had no issues with the brass shavings. Most were either in the case and dumped out easy, the rest were caught by the tray or the quick trim die itself. Granted I have no other trimmers to compare it to, this is my first trimmer but it worked great for me. I used the Lee Quick Trim Deluxe for the 270 and for the 6.5 Creedmoor, and just ordered one for the 357 magnum since I liked it so much.
