Have had one for a while. It works fine and the micrometer dial is fairly accurate. It is easy to pull apart and re-configure, although you do have to experiment a little to get the right seating stem figured out.
My biggest gripe is the seating stem can leave seating marks on some bullets. But with a one-size-fits-all seater, there's no way they could design seating stems that perfectly fit every conceivable bullet.
The directions say to drop the bullet through the window in the side of the die. Doing that with 308 gave me more runout than what I was happy with. Placing the bullet on top of the case mouth gave me much better runout.
I am currently using mine for 6mm arc, and the last round I measured runout on, came in at about three thousandths. I doubt I could load any straighter ammo with anything else.
