The two 10 packs I ordered Tues afternoon were delivered this morning.
They don't have the "2.4x-6x" label on the box that's shown on Buy.com and on Verbatim's site but have the same 95166 Verbatim item # shown on both sites.
The media code is MKM001-000 and my BENQ 1640 shows 2.4x, 4x, 6x, 8x speeds. From other posts, it looks like the 1640 burns these well at 8x.
Now I just have to figure out what's worth burning on them...
