For whatever reason, these don't work on my iMac (dual intel core), using OS 10.4.11. They don't appear on the desktop at all. When viewed through Disk Utility, I'm told that they are "readable" only, & that I can't write to them. When inserting one of these CDs, iTunes is opened automatically (that's not a problem), but when burning music to them & re-inserting the CD later, the CD again does not appear on the desktop, & the CD is no longer recognizable by iTunes! I have other types of Memorex CDs (CD-R type) & they work fine with my computer, but not these. Be wary of them if you have a similar iMac. They might work for you, & they might not! I'm now looking for a CD-RW that works with my computer.

I bought this 25-pack to back up my iTunes library.

Pro:
-Burned roughly 40 songs per minute... wow that's fast (in under 2 hours we burned all 8.65 days worth of our music)
-Read-write capable (at speeds up to 12x)
-13 discs held 2165 songs, and since this was a 25-pack, we still have 12 left
-No problems with writing, no chipped, scratched, cracked or otherwise defective discs
-Comes with a holder and a cover that twists and "locks"
-Case could hold what I estimate is another 8 discs or 33 total if you remove the foam spacer and clear CD-shaped protector
-Minimal packaging waste to deal with and easy to open, no act of congress to open
-Very good price and even better value
-"Sharpie" ink pen writes on surface ok

Con:
-Disc graphics are annoying, no significant clear space/area to write... surface covered with small "silver squares" that dot almost the entire surface

Neutral:
-Top is clear #5 plastic (base is black #5 plastic), good for seeing inside, bad for letting in UV light (hence the nuetral)
-Scratch resistance is unknown. We burned our discs and then packed them away.


Bottom line: Highly recommended. Have had no issues, discs appear to perform as expected.

Lives up to description. Have used over half, and have never had a bad experience. Worth the cost.

Product was new as described, Excellent High Speed Media. The seller was quick and reasonably priced. Excellent product and supplier.
