Great quality discs that burn both audio and data without problems.

Overall, Philips blank CD-R discs store data reliably (at least in my experience) and I believe that an extra minute to burn the data onto the blank disc is well worth it in the event that it doesn't actually burn at the very highest speed advertised.

There are two caveats that many other people note about any brand of this product: when you are burning the data onto the blank disc, don't be surprised if you see that the data is burning at a rate slower than the packaging advertises

Don't store these discs, burnt or blank, in rooms that become very hot; this causes damage to any brand of this type of disc and you could lose data over time

C D record fine

They work as they are supposed to.
