I recently ordered this after pumping without one for over 3 months. Why did I wait?! Very easy to use, can wear as a bra if you'd like or just use when pumping. Allows you to use both hands while pumping to eat, read, brush your teeth, whatever (assuming you can take your pump where you need to do these things). And maybe it is my imagination, but I seem to get a little more when I use this (due to the compression?).
