This is hands-down my #1 preggo product - it gives me the gift of Time! If you have to pump often, it frees up your hands, giving you up to 2 hours a day of productive time.
The Simple Wishes is far more secure than Easy Expressions, and more comfortable for me. The adjustability is surprisingly great. My swollen body has already changed a lot in the two weeks since baby J was born -- i just peel the velcro apart, put it back together and Voila -- perfect fit. I use this about 10 times a day (right now, in fact!).
