Great set (especially if you just want the larger bottles for storage)
I love this set b/c it is an inexpensive way to buy the larger bottles for storage. (We don't use the medela bottles for feeding so I don't need the nipples, but I like the larger storage bottles that attach directly to the medela pump b/c I hear the bottles maintain the immunity properties of the milk better than the storage bags.) The pumping attachments that come with the set aren't practicle for me b/c they are only one size. You can't attach the correct breast pump shield size for you if you aren't the standard size. Thus, these breast shields are not usable by me, but it was worth the purchase to get the larger storage bottles without the nipples (which we don't need).
ProsComes with larger storage bottles
Less expensive way to buy the larger storage bottles.
Comes with 2 Valves & Membranes & sterilizer bags
ConsBreastshields are none detachable (so these are virtually useless to me since I can't attach the correct size for me)
