Question on BenQ DW1640

Haven’t been looking into burners for a while, so I’m a bit confused by something.

3-4 months ago I remember everyone was raving about the BenQ DW1640, but the problem was that they were almost impossible to find.

To my surprise a quick search reveals a bunch of them, what’s going on?

Are they mislabeled DQ60s or something?
Is the drive no longer very popular?


It were replaced by Benqs 1650, 1655 and 1670.
