This product is wonderful. I admit when I first saw it being advertised (before my baby was born) I giggled because it looks pretty ridiculous. However I have to eat my words now, because this makes pumping bearable, I can use my laptop or read a book instead of sitting there holding the bottles in place. Before buying this I tried the Medela pumping free kit, which is laughably poor (and unreliable) in comparison. This bustier is comfortable and functional. Works with any size of Medela personalfit breastshields (unlike their own product) or nipple shields. I can't recommend it enough. If you need to pump regularly, you will want this bustier to save your sanity.
