I have always been intrigued with the closed loop principle for Type 1 management . I have looked at various options over the years and Medtrum , which I have been using for over a year now , are the only company I can see making bold steps towards this goal with a truly innovative and pressing approach . The predictive low glucose suspend function is awesome and has saved me a few times during my gym workout ! I also love the compactness of the A6 pump and the convenience of the patch change which takes less than 5 minutes and only once every 3 days .
