I've burned on ~15 of these, out of two spindles. No problems with them for data yet. I've reburned on a couple, have swapped them back and forth on two desktops and one laptop, with no hesitations. Using two Plex burners, two Plex readers, and, I think the laptop cd-rom is a year old Toshiba. So far all have burned at 4X on the Plex's.
They work in my Sony juke, but not in a friend's car player. I don't use 'em for audio anyway.
The Comp I went to had these almost hidden away, beside the others. It seems like the shelf tag was a little different & I think maybe older. I do remember having to match up the SKU's to be sure I had the right ones. It did not appear to be a weekly sale item. Just appeared to be the normal shelf price.
