I may be one of the few, but I'm dumping the Dex7+ and switching to the Nav.I have had nothing but problems with the Dex and cant use it anymore. I'm not saying it is a bad product, only that it does not work for me. In the recent past I had 5 sensors in a row fail within 3 hours of insertion. I have had multiple times when I would get a high alert and acknowledge it only to have the receiver reinitialize itself. Support told me it was a sensor issue, the district manager told me it was a receiver issue. They replaced the receiver and I still had reinitialization issues. I also found hat more often than not, the accuracy was way off. I had one time for example where the Dex said I was 308 and multiple finger sticks showed I was at 83. Just a bit more than I can tollerate, so I'm going to have a go with the Navigator.
