These are very comfortable and give me the added shape I need.

The inserts were not what I expected. The material was stiff and gave a very unatural look. Because bathing suits tend to be made of thin material, the pads were noticeable in my suit. This item may work for some people, but it didn't work for me.

As an A-cup, I personally use these pads in my triangle bikini tops to add an illusion of a fuller bust.  They look completely natural and even add an asthetically pleasing curve.
