I've had my dextape on now for a couple days. So far it isn't causing me anymore skin irritation than the other adhesives and is sticking pretty well. The edges have started peeling a little already, but that's no different for me with grifgrips or tagaderm.
The best part? Application is truly as easy as they say! I was able to apply one to the back of my arm flawlessly in about 30 seconds. Another bonus is that unlike grifgrips (which I still think are pretty great), the dextape dries instantly after a shower. I always get a little skeeved out by the wet bandaid feel of grifgrips after bathing.
All in all, I would definitely recommend giving these a try.
