My overall experience was fantastic. I really love I can go braless and still feel secure and supported. These inserts helped my insecurities. It's not that I have small breast but without these boomba inserts they look non-existent in some tops. With boomba inserts in, they are sitting perky and exactly where I want them. I highly recommend boomba for others looking for a boost of confidence.
