While I can't comment on the quality of the translation (i.e., faithfulness to the original), since my middle Egyptian is a little rusty (studied it many years ago).  However, it's a wonderful journey, reading aphorisms that ring true today and those that are just plain strange.  Reminds me of the Spanish "Courtiers' Handbook" from the 17th cent. AD.  This book is almost 3000 years older.
