Great patch when applied correctly
Great adhesion and durability when applied correctly.  Held up to showers, sun & beach activities  with a little fraying around the edges around day 12.<br /><br />Not great if you accidentally touch the patch on the sticky side anywhere before or during placement over sensor.  Then fraying around edges occurs within a day and adhesion will fail with exposure to water.<br /><br />Great patch overall, tricky to apply but once you get the hang of it it works pretty well.  I will continue to use these in the summer when my arms are exposed, but prefer the Fixic fabric patches for other seasons.
