It's TSA compliant, but doesn't perform well.
I am using it to transport medicine that needs to be kept cold for several hours while flying to my destination.  The  reason I purchased this specific product is because it is TSA compliant.  I had no trouble taking it through security which is great.  However, the ice pack which came with it does not stay frozen for very long and therefore the medicine which is supposed to stay cold becomes warm in a short amount of time.
