I am very pleased with this product. I bought this to extend the life of my bras during my pregnancy. I didn't want to have to buy a larger size bra to accommodate my rib cage that has expanded a little (I already bought bras in a bigger cup size, not knowing my rib cage would expand too). This hook extender works great! I was worried about it falling off the bra but when the bra is taunt when being worn, it stays in place just fine.
