This laptop looks good, came extremely well packaged, and performs quite well, but battery life is not 80% of a new laptop as advertised. Twice I have tried the laptop without power ... from a full battery, it was slightly less than 90 minutes one time and 60 minutes another time.  Other than that, the laptop performs as expected.  It's a fairly good deal for the money, but the battery life is somewhat inconvenient and disappointing.
