This is really cool. You should add it to the videos in your profile so we can all see the video here

I like that! Always good to see how other people do it (Don’t you do an air shot? And leave it in for a bit longer?!)
Also great to see the interest from the people around the office. Nice to know others are ‘educated’ about D!
How funny is it, that it is harder for me to watch than to do.
Oh, I don’t miss that. I love my pump. Get one if you can…
