Burning works perfectly, the data can be read without any problems from the DVDs. However, so far I could with all DVDs that I have used so far (5/10) no longer delete the data. I tried it with various programs. Either the program hangs during the erase operation and the DVD is over, or they will "successfully formatted" according to the program and will then no longer recognized.
Cheap goods !!! Buy I determined never again! If it would go, I would forgive 0 stars.
