Mya is the most expensive but your paying for quality aswell, don’t take my word for it but I heard that some birkdale surgeons weren’t registered or something?? I don’t know you’ll have to look into it. I have my op on the 6th with mr traynor, and he has been amazing so far and I really trust him! Not even had the op and I would recommend him defo!!! Good luck with whatever you choose! xxxx
