Hi, I tried the dexcom g6 for a month (self funded) I have now a libre freestyle from NHS. If money is no object I would go for the dexcom g6 for the following reasons. It uses blue tooth so up dates your phone every five minutes all you need to do is press the home key on your phone and the BG is displayed on the screen. Very useful if driving. With libre you have to hold the phone over the sensor. States it needs to be within 4cm. Mine struggles to read the sensor through my fleece. I also found the graphs easier to read with the dexcom. I would try a starter pack for both and then decide. You will still need to do finger prick tests as with a new sensor results can be out by one unit. The results are always 5 minutes behind the blood as body fluids are monitored. Also the dexcom will alarm if glucose levels go low so you can take action. The libre does not do this.
