I bought this for my wife because we have a newborn and a 10 1/2 month old.  The older one annoys her when she pumps, and, even if he's not around, my wife loves to multi-task.

She found it so easy to put on and adjust.  It's very comfortable.  My mother-inlaw and I got a good chuckle looking at it.  But we both realize this is a very important device to have.
