Product review (5 stars): Love this travel potty
Love this travel potty.  Like some of the reviews said, you have to be careful when you are twisting it up because it comes apart, but after 2 or three practices you get the hang of it.  It is not rocket science, and is a wonderful travel potty.  Small, but that is what you need out of a travel potty.  I haven't used it with a bag yet, but will be happy when I have to that my daughter will not have to sit directly on the bag.  Easy to clean!
