I have worn these no peeks for quite a while and like them. They don't add volume which is nice. They do help. However, they don't completely eliminate the peeking. If Wacoal could put a petal like the Bali Concealers in these, they would be such an awesome product. Also, if the cute little hat box also had a cheap plastic cage to keep their shape and to wash in AND if they could be two toned so that you don't wear them inside out like a messed up contact lens, that would be awesome! After some use, it becomes difficult to tell which side is in and which is out. There is a tiny little compression that indicates but sometimes I'm too lazy to find it.
