It's no longer watch-sized. The Freestyle Libre3 monitor is precisely the same size as a pair of stacked pennies (US). I'm wearing one right now. The previous Libre2 sensor was much larger, and you had to tap your reader device against the sensor in order to transmit data via NFC. In contrast, the Libre3 transmits via Bluetooth, and does so once per minute, without me having to do anything else. The non-insurance retail cost is about $70 per sensor. With insurance, it can be much lower. For me, the size difference is a real game changer. This thing is so much easier to wear and live with. For me, the automatic update once per minute is also a real game changer. I don't need to tap the sensor with my phone to get a reading, I just open the app on my phone and the data is already there. By all accounts, the Dexcom G7 is about the same size, and because Dexcom plays nicer with other devices, that's the way you want to go if you're trying to close the loop on the CGM plus automatic insulin dosing. For now, I'm super happy to have the Libre3. The app needs some improvement, but this is already a World Series + Super Bowl winner.
