I found my problem was only when I had the pod on my upper arm. I thought that would be a good place for me, but when I'm reaching into the refrigerator or getting into or out of a car, I am always bumping my shoulder/upper arm area and knocking the pod lose off completely. I am too hairy to put them on my belly and since my belly is quite large, I put them on my side, like I did the MiniMed and it works fine.
After having the pod for 1 week, I love it. My endo did not push me toward any particular pump but my pump was 6 years old and when I mentioned the OmniPod, she said it was a very good pump but for me to consider the ongoing cost. I have already met my $2500 copay with my insurance, so all my supplies including the PDM and initial supply of pods cost me $0. I won't have to pay anything until January.
