I've used these for a few years now. They work. There are some definite consistency issues between pages as the labels aren't always cut in the same place, but the other brands I've tried (Avery in particular) had similar problems.
The secrets to doing consistently successful CD labels on any brand of label paper? Background images should be signficantly larger than the label and also cover the hub completely, keep lettering well within the label (1/8" minimum clearance from the edges recommended), and do test prints on plain paper first. And you'll still waste some label sheets, guaranteed.
I've used the labels in a HP4050 laserprinter, a BJC-600 bubblejet and a Epson Stylus 1280 without any problems whatsoever. The 1280 works *very* well, and the quality of the output is impressive even at a low 360DPI setting (although a higher DPI is suggested). I haven't tried the "photo paper" labels, but except in really exceptional cases they wouldn't be worth the extra cost. Laser printers are OK but the labels don't really last that long if the CDs get any sort of wear.
Despite the issues with the labels moving around between pages I'm sticking with the same brand, as all my templates are already set up for them, and they also have had good longevity for me. CD-RWs I labeled in 1999 still have their original labels with no peeling or bubbling issues, always a good thing.
I've never used the enclosed software; I use either GIMP or my own custom label generator program under Linux. There are inexpensive labeling programs for Windows/Mac that are probably better in any case.
Finally: you really need the label applicator to use these. It was worth it, as I've never had any problems with either off-center or misapplied labels. It helps to not curl the label as you remove it from the sheet (keep the label straight as you peel the paper away from it), but it'll work OK even if the label is curled a bit. Don't forget to burnish the label down a bit after it's been applied.
I was planning on buying a new printer some time soon. But this product kind of pushed me to get one faster than my wallet wanted me to. THEY GOT stuck in my printer. I could not get it out, I couldn't use my printer AT ALL afterwards! Totally jammed the printer. I actually had to purchase a new printer after using these labels. I was not happy.
You'll need a device to apply the labels correctly. The labels look best on silver or pure white topped CDr blanks. Silver with silver printing is acceptable, but the lettering will still be visible through the labels in good light.
In addition to the two circular labels there are four other labels per sheet. Skinny ones for the edge of jewel cases, and larger rectangular ones.
Had to edit my review and remove stars. Some labels are cut differently. The difference (~1/8") caused my carefully aligned graphics to print off center and run off label edges. This is a quality control issue.
