As others have said, each area tends to offer different pumps. I have recently started using the 780G and I have to self fund the sensors. I am currently using it in manual mode, which is very similar to any other pump, with the different Bolus options, TBRs, ... I was on an Accu Chek Combo before.
The things I have noticed so far
Positives
There is the option of a slower Bolus delivery.
I find this great as my cannula sites are a lot happier than before.
I now never get bubbles developing in the tubing.
A different valve at the lock on the pump means that it doesn’t matter what orientation you have your pump
If I forget to do the final step for a Bolus it alarms and tells me. This has stopped that sudden unexplained rise after a meal.
There should be more once I start to use the sensors, after my next training tomorrow.
Negative
The only negative I have is that I have to access the pump whenever I want to do a Bolus. I really liked the Bluetooth connection on the Accu Check pumps which meant you could tuck it away at the start of the day and never need access all day, all I needed was the handset.
I do miss the Bluetooth connectivity, but happy to keep going on to the next stage, when I will start to see the benefits of the autocorrections and reductions in background insulin. Keep a watch and I will post as things progress. If you do a search on the forum there are a couple of others wh are now using this pump.
