I previously had the regular pumping bra that is sold by Medela - it worked ok for pumping while sitting on my computer or watching TV, but I couldn't really do anything while I was pumping. You can really adjust this bra to your perfect fit, so you can get it nice and snug so that things don't move around even when you're moving around. I initially got it because I'm on the road a lot for work and got tired of pulling over to pump, and now I can pump while driving (I get set up before driving). I can also use it while I'm getting ready in the morning, doing my hair and makeup, meaning I can sleep in an extra 30 minutes now. Extra 30 minutes of sleep for a new mom makes this one of the best things I have bought in recent memory.
