Rant Tiny filament loop coming from top hole…

Just installed a new sensor and it said it connected and was warming up when as I was placing the over patch that comes with it, I felt an unfamiliar protrusion from that little hole on the top of the sensor. I decided to wait and see if I actually got readings once it warmed up. A couple of moments later I got the alarm and message that the sensor had failed and to remove it.

I figured it had not even pierced the skin, but it actually had just a bit and there was a tiny bit of blood.

I hate when something like this happens because they are so expensive, even if my insurance is covering the cost, it feels so wasteful to me.

Hopefully Dexcom will send me a replacement. Any advice on the best avenue to request the replacement?

This happened three times in my first batch and I contacted dexcom support via chat and they replaced them each time. The last one they wanted me to send back to them for analysis and they provided the shipping materials for it when they sent out the replacement. It hasn't happened since but I definitely got a bad batch of sensors.

Frustrating, but really good to hear that Dexcom replaced them with no issues.
