I already use the blanks very long. Have always used the predecessor (2.4x). Was always happy and have more than 100 blanks (4 spindles) not yet burned the blanks! One should consider whether it is a spindle is cheaper to buy blanks useful where only every 2nd blanks works perfectly or not it better that good Verbatim where you can rely on each. Am completely satisfied. My PC, my DVD player and an Xbox 360 can read the blanks perfectly. So wait but strike no longer.
