HI
@Lordy100 You can set up a monthly Dexcom account for purchasing the G6, it's £159 a month and ensures you have both sensors and transmitters when you need them, it lasts 12 months, I did a single month trial then set this up as I was so pleased with it, I tend to turn the alarm off as would lose 1-2 night's sleep a week otherwise, but if you're concerned with going low over night then keep this on, it's been pretty accurate on the whole, have had a few blips with things like exercising in freezing temperatures when it's lost signal or reporting false readings so always keep your BG meter as back up. At the end of each week you also can access a report which tells you time in range. You can also access reports to see patterns, so it is useful if you want to drill down on control and feel more empowered about adjusting your ratios.
