Absolutely love it! It has option to adjust to size in the back, also brings an extender for the front (great for when engorgement hits) and shoulder straps for support that I have not yet tested.
I used to use a Medela strapless pumping bra but it runs small and I bought it just as I gave birth so now it is even more tight. I was looking for something that had room to grow but still offered secure hold of the pump parts.
I highly recommend this product
