WORST SYSTEM

HISTORY: I have used the freestyle Libre system for many years with success, up until about 8-9 months ago.

NOW IT IS HORRIBLE. Every single sensor dies after either 1) immediately, like the TWO j have out on in the past 24 hours, or 2. within 2-3 DAYS of use.

I purchased a new blood testing monitor at CVS today and will return to finger sticks from now on. These Libre 2 sensors are unreliable, expensive and worthless.

YOU SHOULD FIX THESE WORTHLESS SENSORS. I’m sure I’m not the only diabetic who has had enough.

Not a Home Run

Worked great initially. Then I had to delete the whole app, including history that was being shared with my healthcare provider. I don’t want to have to do that again. Seems like it only connects/scans well for maybe first 12 days after deleting the app and re-adding—only now the data is lost. And then it’s always saying it lost the signal. Very frustrating and annoying. And alarms unavailable. What good are high glucose and low glucose alerts if the alarms are NEVER working. It’s not my phone and everything else is updated.

Libre 2 was much more reliable for me

I never had problems with my Libre 2 alerting me when I was either high or low, but the Libre 2+ seems to always go out of range or off-line when I’m having an issue and it’s right in the pocket of my pants so it’s very frustrating. What good is a CGM if it doesn’t work when you need it the most? I really hope they make updates that can fix this because otherwise I think I’m going to find another alternative

Alerts 24/7

This app is so annoying with Constant alerts. I just want to check my glucose 4 times a 4 and now this app owns my phone. I need to leave it running 24/7, the silent feature is only 6 hour so it screams early in the morning.

Undependable

Scan unavailable notification most of each day. Very disappointing allowing for zero faith
