I like it.
It's a long-play book, that you can (and want) to read from time to time. It is designed for coming back: it has 293 lessons with very clear topic and with some thoughts about this topic. So, if you want to read something about specific problem, then it is quite easy to find thoughts about it.
I like that authors don't afraid of short explanations - for example, lesson 4 have only 5 rows and it's nice, because there is no unnecessary information in it. There is a lot of big books with big chapters where concentration of useful information is actually very low. Not in this book.
I am agree with Tim Lister, who said (on page XVIII of this book):
But I am not quite agree with further "rule of using" this book (also from Tim Lister on same page):
So I think every tester should have their own copy of "Lessons Learned in Software Testing" - it is not that kind of book that you can borrow. It is very useful when you can come back to it whenever you want.
