I haven't had the opportunity to wear it yet, but I did try them out when I got them because of all of the comments regarding the difficulty of getting them on.  I didn't have a problem getting them on, certainly the first attempts are a learning experience.  Key things to keep in mind:  the bra has to have the ability to lengthen the straps considerably, most full support bras don't have the length to do this and also make sure that the bra is turned around (hook side to the front) when you attach the clip, set it low, then turn the bra around and put on.  You can then push the clip up with the tip of your finger to move into position.  They also feel pretty sturdy. Overall seems like a good product.
