After my unfortunate experience with the PDM over the weekend, I am beginning to question if Insulet has a 'quality control' issue with the PDM? I bought my first 2nd generation PDM in June 2009. That one failed in August of 2009 and was graciously replaced by Insulet. The PDM replaced in August 2009 was the one that failed me yesterday, Feb. 2010 (less than 6 months old). I do not leave the PDM in any cold places or hot places, nor has it been dropped or subjected to high humidity such as a bathroom. There has to be a reason why these things keep failing - unless their life span isn't supposed to be very long. Has anyone else had their PDM replaced for any reason? I still love my OmniPod no matter what.....I just want the PDM to last longer.
