It's not the same as the free kindle books each month with your Prime membership; the selection of those is pretty awful. I'm happy with the titles on Unlimited. They don't get the blockbuster NYT best sellers till after they've fallen off the best seller list for a while but it hasn't been hard to find stuff to read.
That what I had, I bought a month when I got my last (sadly deceased) kindle. I might have to try it again (old doesn't bother me, I just didn't like paying for access to a library full of self published and poorly formatted public domain books)
