I have used them, they are brilliant, but i found it hard to get the discs, so i have gone back to printable DVD's. When i did get the discs they was a little pricey. The results are great though, they look the part, infact i coppied a DVD of xxxxxx software and it looked the same. I used a Philips drive, i am aware Pioneer are good but LiteOn are supposed to be the best?
