I haven't used any of them yet but appearance wise they are really cute. I seen some reviews where customers were saying they didn't have as many color options as the photo does but thankfully mines look exactly like the photo. Also, if you're like I was and you're wondering whether there is a single row of 2 hooks on the back side of the extenders, then yes it does. The material seems pretty sturdy but I wish more than just one black extender was included since that is a more common color bra.
