Summary: I have a tower that just seems to burn through this. it is used for a duplicator, but I have replaced 3 of this in the last 3 years. not bad if you factor in that they are used for burning hundreds of discs each every month. overall, very satisfied.

Summary: Most people who know me I am no mechanical/engineer whiz. But with a little effort I was able to order all the correct material from Amazon.com and assemble my 1-7 DVD Duplicator. I was a little confused about the different power interfaces, but was able to figure this out.
