HerRoom Response: Your comment is accurate in that the distance between hooks on bras does vary. This manufacturer made this product with the most average distance on the market.

HerRoom Response: You are correct, that these extenders do not line up with every bra on the market. And, we don't know which brands those are. We do know these extenders were designed for the traditional hook and eye separation measurements by the industry and thus work on most bras.
