Once I had to, separate from the TDK blanks which have for years proven loyal service to me, since the quality of blanks has greatly diminished in recent years, I went on the net to look for other Blanks and struck gold with the CD blanks from Philips. in my euphoria, I ordered the same 2 boxes a 10 CD s and today I regret that I was not only an ordered, because what has been delivered to me there's a bottomless impudence! The boxes came as ordered from Amazon very quickly for me and full of advantages joy I set out, again to copy my songs that I recorded years ago, since it is known that the laser the CD's after a few Years can no longer read. So I put the CD in my player and suddenly heard a squeak and clunk and after a few seconds came the message "No Disc". I thought that the CD was maybe damaged during transport and tried it with all 20 CDs, but I had to find angry and disappointed, that the player has not accepted a single CD. I had with the blanks of TDK also certain problems as it also gave some who could not see the laser, but as a total failure of 100% I had with any manufacturer. Stay away from this product because the CD s are not worth a penny! I wish I had not given a single star for this confidence trick, but we can not, unfortunately.
