It's more than that. It's a big improvement upon DQ60 which was TEAC's mechanical design. DW1670/DRU-820A is a BenQ chassis.
The Panasonic chipset it uses (MN103SA6GSJ) also performs well in LG GSA-4166B.
With some media (MCC RG20 and MKM00), DW1670 produces better quality burns than Nexperia-based BenQ drives.
