As Mel has pointed out, i'm self funding the G6, and have great praise for it after using the libre and wanting an alert to warn me about potential lows, particularly during the night, it was quite a step to jump from the libre to G6 in regards to cost (£159 a month) but it's been a great system in regards to accuracy once past the initial 24 hours and bedded in, however the real game changer for me is the alerts to high/low glucose, as this is where i wanted better control and more stability, it's all done through your smart phone and it's got a great app attached called Clarity which produces detailed reports, customer service is excellent and if i've had an issue they have replaced the sensor, the adhesive can wear thin close to the expiry on 10 days but it's a minor niggle, I wouldn't do without now.
