These do the job, but three complaints:1) They are quite shallow - almost flat. I prefer a slightly more concave cup; my skin perspired much more in these b/c there was no breathing room at all.2) They are very sticky to the touch! I have another pair that adheres just as well, but less sticky.3) The edges are VERY thin, almost like cellophane ... I'm not wearing super-tight clothing to need these, and the very thin edges sometimes get folded over and stuck together.
