I purchased a 50 pack of -R at Staples. They weren't any better than CMC Mag M01 or AM3, in fact I would take AM3 over these. Exact media code eludes me at the moment, it was something like Sony16D1, but was MIT.
Out of my four burners, none of the quality scans were impressive, mediocre at best.
FWIW, I've used 16X +R in the past, which was media code SonyD21 MIT, nothing steller but it produced decent quality burns.
