I just did my 300 mile oil change, the oil came out clean. I strained it through a T shirt and found nothing, the screen was clean and the magnets both had a small amount of black "dust" on them, nothing shiny or chunky to be found. I did find the small O ring in the oil filter was cracked, but not alarmingly bad. The filter is a bit of a chore to change, not as bad as the hinged filter on my old BMW though. My 300 mile impressions are much better than the 225 mile impressions.
