Yep, I feel your frustration too. I think I have a love/ hate relationship with my dex...can't live with it when the numbers are off, can't live without it kind of thing.
I am under the impression that even when they integrate we will still wear 2 sites on our bodies? I will resist integration with all my might if my pump site shares a cgm sensor. Just when the sensor gets in the groove it would be time for a change! I believe the integration is in the single device to manage the sensor and the pump?
Mine are always bent- I attribute it to exercising and movie.
I think with the current technology we need 2 sites because the CGM site needs to be about 2 inches from the pump's infusion site.
