You can get rippling with any implants but because naturelles are more filled they have less chance apparently and have a lifetime warranty. CUI warranty is 10 years I think I had CUI as I’m too planning to have kids within next 10years and I didn’t see point in paying extra for an implant with lifetime cover if I would probs need another op after I’ve had kids after my body has changed, I also went under the muscle so I could still breast feed if I wanted too! xx
