Unfortunately I wouldn't buy these given that it's from Packt Publishing. I've bought quite a few of their books over the years and more often than not they're either full of glaring writing errors that would have been caught if the book was looked at by an editor at all, the code examples have errors that require deep knowledge of said book topic to correct making it hard to progress, or the book doesn't seem to follow a linear learning path making understanding what the author is trying to convey much harder.

Don't get me wrong there are some good books from Packt, but they're much rarer than say a book from O'Reilly or Manning. They seem to just churn out content and not have a rigorous editing process meaning that it's mostly up to the author's writing ability to create something useful.

I used to grab their free ebook of the day when they used to have that and more often than not I would delete or never finish the books because they were just so low quality.
