These are fantastic.
Initially, I bought them and after failing to burn my selected material into successful DVDs with error messages, I got extremely angry and after around 10 tries I had a big pile of new CDs in my bin. However, take heed, if you have problems it wont be these CDs it will be your PC, check your Comp's ability to burn DVD-r's and then if needed (like for me) install some updated firmware for the drive.
These CDs are now out of my Bin and running in my DVD player!
Top Class Product, Amazing Price!
Hope this helps.
