Disks are packaged in a strong container and thy arrived to me in perfect conditon however its about a 1:3 ratio of quality. there is an error on the third disk half the time. Meaning out of the 15 in the package about 5 disks while burning an error occured and i gained myself a coaster. When it works however the speed is great and quality is also good.
