Guardian Connect US

First, the alert sounds can be helpful and obtrusive. It will interrupt music videos and everything else when it makes a noise. Sometimes making them stop all the together. When you get an alert and you go to the app to check what the alert might be, it sounds the alert again right in your face. Also, every time I insert a new sensor. I have to delete the app and reinstall the app and go through all the set up. Every time I put on a new sensor. New updates are rarely available. Every time only seemingly to make the app worse and worse.

This new version cannot be considered an improvement. 1. It does not work if your CARELINK application is placed in a country outside the US. Therefore you cannot recover your stored data of previous months. 2. Most of devices used to measure blood glucose are graduated in milligrams per deciliter (mg/dl), but this new worsening is set to the weird seldom used graduation of millimoles per liter (mmol/l). Therefore calibration requires continuous transformation of units, something never before required. What are these Medtronic “programmers or engineers” thinking of? What a bluff

As opposed to most of the reviewers, I did not have any issues with transmitter pairing and setup — thought it was pretty smooth with straightforward explanations within the app to guide me . . . But that’s about where the positives end. The audio alert settings do not follow what you set them to which is annoying and disruptive(hopefully a quick bug fix). The battery usage is absolutely unacceptable. For a phone that typically uses about 30% of the charge on a typically day, I am now running on fumes at the end of the day with the app installed - I don’t have time for that. Dexcom used about 15% of my battery, Guardian uses 50+%. A broader look at the guardian sensor overall is also not great — the first 6-12 hours of each sensor are awful, often off by 30-50% (this is compared to Dexcom G6 which I wore for 10 days and had only two fingersticks out of more than 30 that were more than 15% off) and seemed accurate immediately after warm-up. The fact that this thing requires 3-4 calibrations per day for second-rate glucose data, doesn’t last 10+ days (all other sensors can) and it’s going to drain my phone battery makes it a pretty big burden to use. I don’t see this having any advantage over other products. It was probably a nice idea when they thought of it in 2014 but it’s already outdated. This product is ‘too little too late’ from Medtronic.
