I change out my purses pretty much on a daily basis, so I have to have something like this or I would go crazy. I also love big purses, so this works great. When full, this organizer is pretty big, so I can imagine it would be difficult to use in a medium purse unless you don't plan on filling it up. It's nothing fancy, but it has plenty of pockets and it made of a sort of material that you can wipe off it you spill something on it. You can also reverse it if you want to.
