Was excited to receive the book at my doorstep today. TBH, i wasn't really expecting a hardcover when I placed the order. Initially I thought it was just a PDF or something downloadable. But yeah, then it brought me to Amazon, thinking it probably be a soft-cover kind of a book. So, I got to say that the hardcover edition was a pretty nice touch from AppSumo.

However the print for that cover, wasn't so much. It was rather a thin piece of paper printed to cover the book. If not handled with care, that piece would have gotten torn easily.
No, I'm not judging the book by it's cover. Because if i had, then i would probably give it 3 tacos.

Haven't started on it yet, but I'm confident there would be something invaluable in there. Now that I got the book, it would make sense of that lost chapter edition which I downloaded a while back.
