I started using the Medtronic Enlite system since mid April, with my Medtronic Paradigm 754, which I believe will work the same way. The main benefits are that it does seem to be generally much more accurate, particularly when you need to calibrate it at least every 12 hours. You can also set pump alarms (vibrate or sound) when you’re reaching either end of your target range. When entering hypo range the pump will ‘shout’ and then shut down basal delivery.
The main disadvantages are self funding costs are considerably higher. The sensor lasts for 6 days but can be made to run for 7 or more. I tried Libre a few times and found individual results very unreliable. They generally showed lower results but in fairness it did show + or - trends well. I think the main advantage is that the Medtronic system works well with the pump and it’s really down to the cost. Hypos to me are now much a thing of the past. I hope this helps, but as in the previous reply I would certainly ask for a trial.
