To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I ordered 5 boxes of these CD-RWs. The first box had 3 damaged discs -- when I tried to format them before using them for a backup, I got a message "Damaged or defective area on disc." When I looked at them I could see many scratches on the shiny side (not all in the same place) on the discs that got this error message. On the positive side, the undamaged discs work fine, and the slim jewel cases do save space.
I wonder how many of the people who reviewed these disks even *considered* that the problem might be their drives or software? I've burned at least 30 of these disks in 6 different burners, by 5 different companies (Sony, Phillips, Acer, Yamaha, Lite-On). And for software, I've used the most recent versions of Easy CD Creator, DirectCD, Nero Burning Rom, Nero InCD, NTI Cd-Maker, and NTI FileCD. Not one problem. I've got 20 or so of these disks waiting for their turn, so I won't need new ones for a while. When I do, I might look for a better price, but I definetely won't need another brand or model.
