Input:
I have had this burner for a year and I have NO problems with it. Yes it is not super fast, it is 4x, but it is good for a USB port. I burn about 10 CDs a week and it has never given me any problems. I made a great purchase and this burner is so much better than the HP USB CD burner. Definitely a great purchase!
