Braza brags on their knit fabric and soft nipple pad, but those are the very things that make this product near useless.  They are as comfortable as Braza says, more so than a lot of their competitors.  However, they show under almost everything.  The soft fabric is thicker than the usual nylon and shows a petal or heart shaped outline with a puffier circle under most clothes.  Basically, if the fabric isn't thick enough to hide bra seams, it's not thick enough to hide Braza's stickies--which almost entirely defeats the purpose.

These probably would work well for nipple protection during topless sunbathing.  And with certain outfits they do work okay, so depending on the particular thing you need them for it might work out.  Since they are a touch more comfortable than average, I give them 2 stars instead of 1 star, but there are certainly better products out there.

(I also have my doubts about getting them wet because of the fuzzy texture of the fabric, but I've not tried it so can't say for sure.  So if your plan is to wear with a swim suit, you may be disappointed.)
