The bra extenders accomplish their function well, however they don't fit in every double-clip bra that I have because the separation between the top and bottom hooks aren't the same size. If the distance of the bra's hooks aren't the same as the extender, the risk of unhooking exists. I have been using them for the last 2 months, and they came loose just once. Other than that, they appear to be reasonably well made. So much better than the ones I originally purchased at Victoria's Secret. And less than HALF the price.
