I am still using my first strip, so cannot say anything about whether it lasts as long as indicated in the advertising. I am using the strip for a mastectomy scar, so it would have been helpful if a patch with a curved end had been available, rather than a completely straight strip. The adhesion is good, so far, and I am pleased with the product. Since there is no compression garment (that I have seen) dedicated to mastectomy scars, I have found it necessary to wear a soft, long-body bra at night in order to keep the strip in place. This feels a bit weird.
