I have ordered and used 200 of these disk through another sorce at a higher price but still lot lower price then sony. Sony cost $20.00 for 10 disk. Thats $2.00 a disk. These will shipping cost .40 a disk. that means you get 5 disk instead 1disk. Heres the difference the sony blue colored disk have a better anti scratch coating. The cheaper disk are not as well protected and do scratch easier but if you take care of the disk and pay a few bucks for paper sleeves they will be ok. Its a great buy if you want to save money for everyday taping. For major events birthdays of loved ones or births I use sony evrything besides that I use TDK.
great buy for the price
