The first question I would ask that I just realized you didn't say anything about is can the DexcomOne be calibrated? If not then it becomes the same as the Libre. I would think if the DexcomOne got approval it has to be decent. But calibration to me would be extremely important.
I hadn't heard of the DexcomOne at all in the US. I have to wonder if it will be introduced here. Our insurance (92% people have) pays for most of us type 1's here in various amounts of costs or free, and Dexcom is charging the insurance companies an inflated huge amount for them. If you don't have insurance you usually get them at $300 for a months supply, plus you have to buy a transmitter, that's more than they charge people overseas for them. But the Libre is gaining in popularity pretty quickly because they are promoting it for the huge market of type 2' here. Insurance is starting to cover Libre's sometimes for type 2's. But even without insurance it's only $37 a Libre sensor so a lot of people self fund it for the convenience of a sensor. I'm sure Dexcom would love to get a piece of the action since there are so many type 2's, but they would need to have a cheaper version for type 2's or for their insurance to decide it's worth it to cover it so...that becomes interesting.
On restarts...........I had been extending my sensors to an average of around 26 days and I calibrate them to within .3mmol (or 5mg) of accuracy. I get them free but I like the accuracy of a restarted sensor better. It takes less work at calibrating it to get it accurate. Although soaking a new sensor helps some. A restart I can get pretty accurate within 24 hours, but a new one takes more like 48 hours and then maybe another calibration 5 days in. I have gotten up to 45 days on a sensor. So I have a huge supply and I think that might be why some are not lasting as long as they used to, now more like 15-16 days. I use the old stock up first and I am now using expired or close to expire ones? I am thinking of trying some of my newer ones to see if I go back to the 26 day average I had. But I really like restarts better. Plus it's just easier lol!
It's wild how some people have trouble with it even lasting the 8-10 days and others like me can wear one for a long time with no issues. I check mine but they only get inaccurate suddenly in a day, so it's easy to tell when they need to be switched.
