I've bought this organizer in two different sizes, and it just doesn't work for me.  It keeps falling in and collapsing on itself and getting scrunched into a ball at the bottom of my purse.  I can't seem to find anything.  I wish the top zipped shut instead of being open.  The snaps on the sides help keep it together a little bit, but not good enough.
Prior to this I used a small Baggalini purse that was very structured, tons of pockets, with a zipper top.  I actually put that purse inside my bigger purse, and it worked to keep everything organized and portable.  So basically a purse within a purse.
This doesn't work as well.
