These do what they say they're going to do, but can be tricky to work with when you are alone. It would be easy to hand these to another person and have them attach it to your bra. Its difficult to put these on the bra before you put on your bra, because the clip doesnt stay on without tension. Its a lot of bending and reaching to attach these to your bra once you are wearing it. I end up not using these and they sit in my drawer, because its too much effort on your own.
