I have been on dex for about 5 years now. As someone with hypoglycemic unawareness the ability to have friends and family see my numbers and get alerted if i go out of range is invaluable to me

I have had dexcom for a few years I love this thing

I have used both and I personally prefer the Libre2 for two reasons. 1. It is MUCH less expensive than the dexcom, and 2. It lasts 4 days longer. The only downside to me is that the app is a bit clunky, and alarms only have 1 volume- loud. I'd still use my Libre2 over a dexcom any day.

The size won't be a problem it's the width of a dime and sometimes I forget I have it on but it really helps me
