It's "good" in the sense that if you fill out a form (probably manually entering things in boxes in a web form), you'll probably have a PDF in your email within 2 or 3 business days, so long as nearly any library anywhere has a copy (licensed electronic or on paper).

For a hard-to-find article not really available anywhere else, that's pretty neat.

For something you could just get on sci-hub? Nah.

In the early 2010's, I was able to find stuff through ILL that I couldn't find anywhere on the internet. Not sure how extensive SciHub is nowadays.

nor in 2019!
