Lovely shape, very lightweight, nice soft material. Would be great if they had more than 3 sizes so those of us with one remaining boob could get a closer match.

Took a long time to find a prosthetic that was right for me. Very good quality, great fit, comfortable to wear and natural looking. Also good value for money. Gives me confidence when wearing.

It is really light and good quality. The prothesisyou are given by nhs is far too heavy, and this is perfect. And really good value!

Great, comfortable, would recommend

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I’m normally a size 34D and I found the ‘small’ prosthesis fitted well (I bought the ‘medium’ pocket to go with it). However, I do already have a small amount of tissue on my mastectomy side from a first round of fat grafting, plus latissimus dorsi muscle flap. Very comfortable and would recommend. Very grateful to M&S for continuing to support the breast cancer / mastectomy / reconstruction community.

These inserts are very comfortable, they fit in the mastectomy bras nicely. Lighter than the prosthetic ones you get from the clinic.

Useless

Originally posted on marksandspencer.com (UK)

Terrible! It was so light. It had no weight to keep that side of my bra down. In fact during the day it seemed to move up out of the bra and over my shoulder. Very uncomfortable and useless. When I had my mastectomy and was given my prosthetis. I was told it was to match the weight of my remaining breast to avoid stress and prevent back ache. I am older ( 84) and have lost bulk but there must be some weight.
