To be honest, I purchased this item because I needed an item to reach the free delivery amount :)
I've never spent so much money on classical scores that are available in public domain (I am an advanced amateur, not a professional concert pianist) but I always wanted to treat myself with an urtext edition, and I'm very much into Chopin music and very interested in all possible versions, manuscripts, etc.
It's totally worth it! The quality of the print is exceptional, the book is easy to stay open, even when you turn pages. There are detailed comments about all the possible editions and differences, bar by bar, phrases, articulations, etc. An absolute must for a Chopin lover!
My only complaint is that I've seen a few slightly odd fingerings that I would say are rather erroneous but that's if I have to be picky.
