Have had saline breast implants and silicone. Completely night and day. The silicone look and feel more natural. They actually lay down when I do at the beach and don't have a wavy appearance like the saline did. The saline also did not adjust to my body temperature, it was odd. If the water was cold and I got out and the air was hot, they stayed cold even though, I would warm up. Not a good thing.
Love the new breasts.
Should these happen to wear out on me, just like a set of tires, I will replace them.
