Rated 5 out of 5 by from What can i say it`s an LG the best in the field. This is my 5th purchase of an LG product in the last 10 years. What can i say it`s an LG the best in the field. My first was 50" LG TV in 2011, it`s going strong and has never gave me a problem. Since then i always try to buy LG products, if the price is right. I highly recommend LG products as they seem to be a better build then most products

Rated 3 out of 5 by from Not As Durable As The Internal Drive I have purchased the internal drive version and it works great. It works just as well but it's not as durable. The soldering that connected to the mini USB port broke off

Rated 3 out of 5 by from If I can get the software to load... Can't get it to work. Tried to load the software and a message came up saying that it was for LG products only! Should have looked around at other burners before purchasing it. I have heard good things about LG from friends and reviews but this experience kind of sours me on LG.

I have this blu-ray writer and I love it. Unfortunately I can't find the USB cable to connect to the computer. Does anyone know where can I get only the USB cable? Thanks.

Asked by: CarlosElCentro123
The cable you are looking for is called a USB 2.0 (Ytype). It contains both a micro-usb end as well as a mini-usb. There are many 3rd party vendor websites that sell this cable. ^CP
