Sia, Fortunately I got a refill yesterday, but waited till today to attempt it. I washed that portion of the arm, then used an alcohol patch on the same area.

In taking off the first one, I noted a mini needle going inside the skin. I figured I may not have pressed hard enough on the dispenser, so I pressed harder this time. Then I did not check on it for over the hour needed.

I had checked more often on the failed first time.
