Pros - inexpensive, bulk, and works well to clean light to medium soiled brass. I also found less of this media gets stuck in the primer pockets and flash holes of cases after sifting.Cons - very light and dusty media. Tends to stick everywhere due to static electricity. Does not clean as good as a heavier media. Does not last as long before needing to be replaced.That being said, if you know that before hand and don't expect more you won't be disappointed. The amount you get for such a low price is hard to beat.
