Yes, my Hba1c s to date - although I haven't posted the last 2 which have both been 6.5.
I didn't make my post very clear, sorry! The dexcom I used is a CGM. As far as I'm aware, dexcom don't do pumps. I have an omnipod pump, which is a patch pump - so called because it is tubeless.
I believe the Medtronic pumps work the the dexcom. To be honest, all the pump companies are either launching or are close to launching a pump that is CGM compatible. That's not to say they are closed loop systems yet, but they may alarm, or suspend insulin in the night if you are going low.
For me the cost of a CGM is prohibitive, but I am looking forward to a future where prices go down and hopefully the NHS can support.
If you have any questions regarding pumps, ask away. There are quite a few of us on here, using a variety of pumps. I certainly wouldn't go back - my pump gives me better control and a greater sense of freedom.
