I totally wish I would have purchased this when I very first started pumping. It was suggested my Amazon a few times and I just kind of laughed thinking it would be a waste of money. I LOVE THIS PRODUCT!! Even for everyday use at home, it's great - but I take it to work and look forward to using it on a road trip next week (already had one without and it was a nightmare!). It does take a little adjusting to make it fit right for you, but there are several ways to tweak the sizing (velcro and extra zipper piece), so you just have to work with it until you get it right.
