Well done, Alex! You maintain good eye contact throughout and the camera is able to focus in on the important parts.
I agree with @Dave44 that it’s important to keep the two fingers away from the collar when inserting a sensor. You were obviously aware not to pull up on those two fingers before you pushed down with the thumb on the plunger. I have made the same mistake many times but I’ve never pulled the ring up before sending the plunger down and wasting a sensor.
Dexcom makes this point because I’m sure with the thousands of people using their system, this has happened a few times.
Nice work with the one-handed application of the reinforcement adhesive.
I started using this style sensor/applicator back in 2009 with the Dexcom 7+. Before I inserted my first one I watched a YouTube video. I found the video format very helpful.
Your voice was steady and clear. Your sunny disposition combined with obvious confidence builds confidence in the viewer, too. Good job!
