This is compared to the Verbatim DVD standard precision engraving is there, the failure rate close to nil, the duration in time simply excellent, I have burned DVDs (Verbatim) for many years without loss data.
Although the speed of 16x can be achieved, I suggest you use a speed of 4x or 8x to secure your burning.
Conclusion: great product, cheap that will fill you in a family or professional use.
