Query: Unusable disks, do not waste your money

Wow, I'm just amazed at how lousy theses disks are. I've been burning for years (since '97) and this is the first time I've ever encountered unburnable disks.I purchased a spindle of the Memorex 52x 700 mb disks and have tried to burn 'em on numerous different burners/computers.No luck the disks just don't burn.Wish me luck on returning this garbage.
