I'm on an omnipod ,and have been since March. I wear mine on my upper arm and have had very few issues with it, I sometimes stretch the 3 days out until the empty reservoir alarm sounds, but it behaves beautifully, the smallest amount of insulin it can dispense is increments of 0.05 units or 0.0005ml. I was taken by the wireless nature of the device as the conventional pump had me wondering about sleeping with the cannula trailing across the bed but the pod is very in obtrusive. Now although the pdm has a built in bg meter, I continue to use the accuchek mobile meter as it is more convenient than inserting test strips each time. It seems pretty robust, and the pods stay where you stick 'em...
