For me, at this time, I'd love to give up the G5 transmitters/receiver and go back to the G4. So much less expensive, even with insurance. And, the kicker, SO much more reliable. I'm on my 2nd G5 transmitter and I have continual issues keeping it connected both both the receiver and the smartphone. I'd expect the smartphone issues, but really never experienced that with the first G5 transmitter I used. The second transmitter has been a real pain. I have to at least twice a week go through a full reconnect routine with both types of receiver setup. I worked with Dexcom a few times to remedy, but didn't get anywhere with that. Decided to try living with the problems for a while, well I took too long, now they won't support this messed up transmitter. I'm not very happy at all. The transmitter really is a very simple device from my opinion, and shouldn't cost as much as they do. Now that I have to buy up to 4 a year rather than the 1 a year like I did with the G4, I'm not happy at all. Dexcom made a greatly accurate system. But their greed is getting the best of them in my opinion. We can only hope that more competition brews up to push Dexcom into being more helpful rather than less helpful as they've been with the G5 units. Which seem to me to be made mostly for forcing faster turn around on sales than for extending the service they provide with this tool.
