4.5 For the price these are fine lightmuncher | 17/06/2012 | See all lightmuncher's reviews (1) I have bought these several times now. I have realised that the failure rate is about a third of the disks. So I re-copy the video or what ever I am recording on the disks. I calculated the cost against the others to see if buying the more expensive disks would be better. But I know there is no guarantee that they would not have a failure rate either. These are the reasons I only gave it three stars, but I am still buying them due to the low cost. The video seems to be more problematic than say files and images. Hope this helps you in you quantifying if these are what you want as I am now purchasing more.
