Mr. Singh is brilliant! Such a good surgeon and a genuinely lovely guy. MYA swapped from Allergan to Mentor a few months ago now, they’re just as good, still a really high quality product. They use mentor implants for cancer patients and the guarantees are a little better from Mentor. Mentor are made by Johnson and Johnson…I think that says it all really. They most defiantly do, do round implants as well. But, if you’re unsure about them, just talk to your PC or surgeon about your concerns or for more info. I had to meet with Mr Singh for a third time after they changed manufacturer, as I was set to have 525 round Allergan naturelles, he explained the difference the guarantees, and benefits etc.
