Query: These are alright if you need coasters.

About 1 out of 5 of these discs ended up in the garbage. I only burn at 4X and even still, 1/5 of them reported an error. I've had my CD burner for a year and a half and have never had this problem with Memorex, Imation, or Fugi discs.I bought these because of the Sony name... but trust me when i tell you - STICK TO MEMOREX!
