Our daughter has been on the Freestyle Navigator for nearly 2 years, with much success! Last night we encountered a problem with it, I called Abbott this morning only to find out they are not replacing any receivers or transmitters at this time, and will offer us a refund to purchase a new product from another company. I would love to hear pros and cons on different sensors your children are wearing. She does wear the omnipod, so I am leaning towards the dexcom. I sure hope this process goes smoothly. I'm sure our insurance will have something to say about this! I can't imagine living without a CGM for too long!!! Thanks for your help!
