You didn't miss much. It took 20-30 minutes each pass, plus the extra cost for the discs.
But even if you were fine with that, it came out too light under actual lighting conditions, even after you burned it twice, which defeats the use case of making it look professionally labeled. For home use, a Sharpie beat it in every way.
Huh, that wasn't my experience. I mean, it absolutely was slow especially with sufficiently complex labels, but they generally came out fine. Granted, you absolutely couldn't just drop any arbitrary image into the LightScribe software and have it come out looking good, you'd have to mess with the contrast, but black-and-white text and line art would come out fine. And more legible than Sharpie, with my handwriting.
For a very low-sales side business (my father's hobby) the discs looked sufficiently professional to impress the people buying them — mostly his friends.
