It's a great bag, looks great and stays slim on the back. Can fit a surprising amount of stuff in it! I feel like the main section could have a few more dividers and pockets to help divide up some of the space.
Should be noted that the MacBook 16" doesn't quite fit, with its corners sticking out the top just a bit. Still keeps in the bag pretty well, but it cannot zip up. For cases like this is could be nice to have the back handle be sewn behind that back pocket so that it's effectively sealed when holding the bag or buttoning the handles together. However this last point did not contribute to the 4 stars rating, it's just some thoughts.
