I used to think the exact same thing, somehow I think I was really just afraid that someone would see thing thing embedded in me if I ever had my shirt off. When I finally got a pump I realized that it simultaneously keeps itself out of the way while allowing me quick access to my (approximate) levels. I can give my self insulin mid sentence in a board room meeting. I can see my levels dipping and get a lifesaver before it sets in. The worst that ever happens is that someone asks what the hell I am doing with a pager.

In short, the pump CGM combo it is the best thing I have ever done.
