Wow - how was I pumping before this??  Pumping used to be so annoying because I'd have to sit there and not be able to use my hands for 15 minutes.  This hands-free solution is a life-saver.  Stays on, is tight enough, good quality.  I haven't tried washing it yet, so hopefully it holds up.  Can't imagine pumping without it.  If you are planning to pump at all get one!  I use it with my Medela Pump-in-Style Advanced.
