By-cons, I find the section on preparations (realization of decoctions, infusions, syrups, etc.) is not detailed enough in my opinion.
And the other small Downside is the ranking by the Latin name that is NOT at all practical to locate a plant.
Note that I am a beginner and I have to buy this book minitier the identification and preparation plants.
So in conclusion I would say it is fine to start identification, but it will take against by finding a more complete book regarding the preparation of remedies.
