Review (5/5): Great little products
I bought these more to alter my bra for racer-back tops, which they do, and they are great for that. It takes a little practice to get them set up properly, but I like the way my new tops look without having to buy new (expensive) bras. I can't comment on the cleavage part, I haven't really noticed all that much of a difference. But, for what I bought them for, they are a great product and bargain at this price.
