Very good - work flawlessly; can't speak for longevity (hence 4 stars, not 5).

Better by far than Memorex, Verbatim, or Amazon Basics - all of these have proved unreliable, and picky about which recorder they're used in. These JVC/Taiyo Yuden discs have worked perfectly in three different recorders so far, and their plain appearance is a blessing - easy to write on, no printed drivel obscuring areas of the disc. I must say, Sony, TDK and Maxell have always worked well for me too, but not at this price! These discs can't be beat, and if I start to run low, I'll be re-ordering. Delivery was fairly quick, too.
Afterthought: If having a solid plastic container with a spindle matters to you, you might not be happy; only the shrink wrap holds these together. This doesn't matter to me.
