Benq 1650 and 1655

What’s the difference between 2 devices?
I’ve got 1650 and as u can see in the photo there is writing something 1655(B)…

1655 can do lightscribe, the 1650 cant.

well i’ve changed my 1650 to 1655 but i can’t figure out the chinese 1655(B).
Is it possible for the 2 devices to have the same hardware?

if lightscribe works with a 1650@1655 they probably have the same hardware. but i doubt it.

the BQR-DW-1655(B) is the same for the 2 devices…
Is there any review for 1650 so we can compare them?
