I am a long time user of the Maxell Music (Audio) blank discs & have always been happy with the product, although I normally buy them in the 30 count spindle. The sound quality is always excellent & since I am frequently making copies of promo discs or music to learn for his band for my husband who is a professional musician , that is a very important factor.This time though, I have used a little over half of this 50 count spindle & have already encountered 3 useless discs. While it is not unusual to occassionally find a bad disc, this does seem to be a higher than normal percentage. However, since this is a sealed product from the manufacturer, I do not hold Overstock responsible, I just hope it is not an indication of future trends. I have always been pleased with the service & delivery time from Overstock & this will not affect my continued use of their services.
