They serve the purpose, but the hooks, once attached, kept coming loose and they were not "tight" and "snug" on the hooks. I actually had to get some sewing material to "secure: the areas that keeps unhooking. Maybe others are not having this issues with the hooks on their bras, but on mine, these extenders are very loose on the hooks and you get a lot of play. I like the extenders themselves for the extra room that I need since I have a wide back, but it did take some "creativity" on my part to actually make these tight. However, this is for a strapless bra, so now. all I have to do is put it on over my head and pull it down over my girls and adjust as necessary. I no longer have to worry about the hooks coming loose at any moment and causing an embarrassing moment out in public. However, I cannot give 5 stars for the fact that one may have issues with looseness and it's not the perfect snug fit on the hooks on every bra.
