Well I have the Benq right here for testing
I do not know if it’s worth the hassle to ship it back.
I’ve not done many tests with it yet, just fitted it into my computer really.
Average read and write speeds is a bit lower than with Lite-On.
Media compatibility is varying, some writes at higher speeds with Lite-On, some writes at higher speeds with Benq.
But the written discs seems so far to be good quality!
It’s a less noisy compared to Lite-On
It works good in CloneCD and supports backing up the same protections as Lite-On.
It’s up to you
I do not know what I would have done, if you care about noise and do not care about having the BEST speeds it should be ok to keep it.
