I’m a Dexcom user, and I’ll be keeping it. Having a system that transmits numbers continually to a device that will alert me when things go bad is key for me. The fact that you have to scan the Libre sensor to get the values is a huge drawback, as it means you don’t get high and low alerts and are still forced to rely on your body telling you if you’re off.
However, I can see some use for the Libre if it is inexpensive enough. I have a friend with type 1 that can’t afford Dexcom and insurance won’t cover it at all. I think the Libre might be good for him, IF the price is really significantly lower than Dexcom. At this point, though, all I’ve seen are a lot of claims that the price point is lower, without actual hard numbers to show how much it will cost.
