I didn't purchase mine from Amazon but I did buy these online last summer (eBay) and am now looking for another style as these did not work out for me, so I've only worn them once or twice and they are in my GoodWill drop-off bag. I did find them to be very heavy when bending down as another reviewer mentioned--and way too hot to wear in the summer. Beads of perspiration formed  beneath the silicone inserts, dripping down and tickling to distraction as they pooled in my bra cup. They were also visible past the edges of my bra so I had to be very careful not to wear anything that was cut too low thus revealing my secret. They are also too wide for my 34" chest, making me look like I'm flat and fatty in the upper body instead of well endowed. I weigh 110# and am 5'2"--but it doesn't take much to make a short person like me look like I gained 5 lbs with this spread out bust bulk. It is too thick on the lateral edges of the chest instead of being fuller in the middle which is what I was hoping for. I am a cross between a 34 A and B and need something to fill in my bra a bit better, but this really only fills out the sides and is too wide all around,extending past the bra edges and just makes me look like I have a flat fatty chest. I am about to order a wedge silicone style that has a push up effect according to the reviews with the hope that it will be cooler and tolerable for the summer because it has a smaller surface area, and that it will give me a perkier look with fuller shape in the middle of the cup. If that doesn't work either, I'll just have to accept what nature has given me, I guess, unless someone has some great tried and true recommendations to offer...
