Does anyone here use the WhisperWear pump? I'm thinking about obtaining one for use on business trips, because of its small size and ability to use a battery pack, but I'm not sure if it's really going to be adequate to produce what I need to produce over a 2-3 day trip to not deplete my freezer stock or compromise my supply. I might still get it to try and just take both that and my mighty, dependable Whittlestone on the first trip, so I can use the WW during the day when getting both privacy and an outlet in the same location can be a pain, and the WS at night and first thing in the morning when I really get most of my pumping done anyway, but that does sort of defeat one of my two purposes, which is to have something small enough to stuff in my luggage so I can get through airport security with the requisite only two bags. :)
Anyway, I would appreciate anyone's thoughts on the adequacy of the WW over a sustained period of exclusive pumping. Thanks!
