Worth looking at more than one prosthesis if you find the first uncomfortable. I have used Amoena from the outset and am happy with it, but I note @BlackWidow’s comment about Trulife and will have a look next time I get a replacement (a prosthesis lasts about two years, you can claim the rebate every two years as well). I’m in non tropical Melbourne, so don’t have a problem with sticky heat much and wear mine with a bra with a prosthetic pocket. I switched to an Amoena bra (Mona, stocked by Myers) a while ago and like it. Best wishes.
