I bought it from Transcend PC and they were happy to replace it. Looked slightly different than the previous, but so far works fine. I would consider another drive next time. It is nice fast and quiet. Much quieter than any Mitsumi drive.
Drive comes in a retail package at an awesome price.
The first one that I bought broke on me in one week. I'm running a Pentium 250MMX with Windows98. I found that my Sony 16x was much, much quiter then this drive. I'm not too happy about it. This is a high quality cd-rom drive from our Taiwanese AsusTek friends.
