We are absolutely on the border with being in or out of warranty on our Omnipod system. We asked for the conversion as soon as the FDA approved and were told to wait. We made contact today and provided them with updated insurance info. This insurance goes directly through insulet so there should be no delay however, our four year period is up very, very soon. If they delay, we will have to buy the system, if they treat this fairly, we will qualify for the upgrade under warranty. The system was initially sent to us on 7/14/2009 - do you think the warranty is based upon the shipping date? received date or the date that we began using it? Either way, I am hopeful that they will be honorable and not delay sending this so that we would be outside of the warranty. Does anyone have any idea about when the warranty is based on. Thanks for any advise.
