We're had a weird thing lately.....we are on the 9th pod over the past month that the pod starts screaming while I'm filling it with insulin....... Granted, Insulet has replaced them (and we have 2 more from last night) but honestly, it's a large waste of insulin, and it does make me wonder (especially when my husband keeps crabbing about it .....how well made are these pods? I always wait until the insulin is delivered in the middle of the night, because it's always been in the back of my head, "what if it doens't stop> what if it overdoses?" I realize it's highly unlikely...but then again, the service reps seemed surprised about the pods that when crazy and had me send them back. anyone else worry about these things????
