I agree with the reviewer who said the shoulder strap was slippery.  It is, and you have to pay attention so it doesn't slip off your shoulder.  The bag itself is very well organized and was perfect for me until I needed to carry reading glasses with me.  It all goes in there, but not as well as it did before the glasses.  I got rid of the small little purse that came with it since I considered it useless.  All in all, I like this bag.
