I've had a BA with Dr Suporn and had mixed results, though I don't believe this was due to the Doctor's skill but rather just an unfortunate outcome that can happen with this type of surgery.
I can't speak to the issue of pain, because I lost most of the feeling in my chest, so I never actually experienced any pain from it at all. There are important things to be aware of before having this surgery, such as the need for regular breast massage. I had some incredible muscular pain in my arms that seemed to be due to scar adhesions in the underarms (not the fault of the clinic at all, just the way I healed. The clinic were very helpful with information on how to fix it). This pain went away eventually after regular excercises suggested by the clinic.
The placement is balanced and even and I certainly have cleavage. I worry that they are too firm, but I think that is due mostly to the type of implant used (the benefit of this implant being that they don't ever need replacing and are far more durable than others).
I do wish I had feeling and that they were a little softer, but that's hardly the fault of the Doctor. Overall, I think Dr Suporn and the clinic did a great job and were always very helpful and attentive with aftercare issues. I say go for it!
