I just replaced my GSA 4163B for a Benq 1640 because I keep reading good things about the Benq 1640.
I just replaced the firmware, nw on BSMB. SB-on/on, OS-on, WOPC-on
Here’s the media that I have:
Writes at 12x in LG - 97 quality
8x in 1640 - not so good…
4x on LG - score: 95
8x on benq (but actuallty writes at 4x) - score: 78
