[QUOTE="Mainsail, post: 2319938, member: 31405"] I am in exactly the same position re the warranty which ran out in Sept but I have pretty well decided to stick with the 640G. That may sound crazy but my reason is that I am using a Freestyle Libre to control my BG and have been getting really good control for the past 4 years. This of course means that I have to transfer my BG readings manually from the Libre into the Medtronic pump while using the Libre to understand what is going on. My logic is that no matter which model of Medtronic you go for - even the new 780 - you still need to input your carbo figures manually anyway. While that may seem a nuisance, because it involves taking the pump off ones belt (or wherever else you retain it) and entering the carbo (grams), you can at the same time manually input the BG figure. Abbott have dramatically improved the accuracy of the Libre and I find it is in pretty good agreement with finger prick tests these days - to such an extent that I very rarely bother with finger pricking. The only time I would finger prick is if I have gone below 4.5 mmol/L AND the Libre is indicating I am still falling OR at the same time the pump shows I still have active insulin that is likely to take me into hypo territory. So the number of times one uses a finger prick test is dependent on how confident you feel with using the Libre and that confidence builds up with increase use when once you have your pump settings adjusted properly. It is still important to get the pump settings right but that applies whatever your choice of pump. So the big downside for me is the need to remove the pump many times a day to input carbo manually since this almost defeats the benefit of having a CGM which takes up more valuable body space that cannot be used for the infusion set. And additionally the real killer is the need to calibrate the sensor regularly. If you don't need a sensor for BG then that problem goes away and you might as well stick with the old Medtronic 640. Not everyone will agree with me and may prefer to let the pump do all the work for you , in which case I would imagine the 780 would be a good bet if you are allowed it. I just believe that one needs to have a good understanding of BG control, in which case I cannot see much benefit with the 670. But if you like the Libre there is no point in having a pump with another sensor. [/QUOTE]
