I thought I was getting a quality product but after installed it made a rumbling noise. Call Yamaha and said it was defective, sent me a replacement; it worked fine for a week then it just Quit!Yamaha CS refused to replace the second one. Even though they sent it directly!Most upset, bought and HP cd burner and have not had a problem yet.It was true what my frinds said, go with proven quality even if you pay a bit more.
