You have to be very carefull here as some recorders will only write at 3.3 speed but a older pioneer 112D writes them at 8 speed
as in the new pioneer i got with latest firmare is 3.3
But they did work perfect on 112D
But once written on the other cd writers could not erase so scrape
Id suggest you buy just 1 first to test
so strange rating
0/10 on some writers
10/10 on others
when they work they are perfect as in copying back to hard drive no faults or errors and dvd movies no jitters
