I had purchased and used several brands of DVD and Blu-Ray burners over the years and when I purchased my first ASUS Blu-Ray burner 4 years ago, I was impressed. At that time I was burning at least 10 DVD's or Blu-Rays a week or about 50 a month with no coasters. In fact, it still works perfectly but I decided to buy this ASUS burner because it has the M-Disk option that I find useful in storing photos and music that I converted from vinyl. I gave my old unit to my son who is burning disks with it without any issues. So, if you are looking for a reliable and quiet Blu-Ray burner, look no further and buy this one, you will be happy that you did.
