Has anyone tried the newest tool from Lee precision, supposed to ease and speed up the trimming process...

I picked one of the "deluxe" versions that deburrs and chamfers as it trims along with the dies for 223rem and 308win and thus far I'm much less than impressed with it. It seems to only take a couple thousandths off of any case, regardless of how long it was to start with and half the time the cases still have burrs on them. Even the few I do manage to get trimmed and deburred take me at least 3 times longer than using the zip trim and case length gauge setup...

If anyone has used any of these with any good effect, maybe I'm doing something wrong or there are some pointers on its use...

Input would be appreciated.
