Just got CH20L from him. He not always on LYN so replying PM have to wait some time but after confirm he will ship the unit asap. His packaging is good, full with foam in a box and tape a lot.

Give a short review.

CH20L is detected as "hp BDDVDRW CH20L ATA Device" in device manager, so i think should be OEM for hp pc.
CD, DVD, and BluRay Disc all reading good, didn't test the burning feature yet.
Blue LED indicator, better than green one
Good reponsive, does not took too long to read a disc.
