Hi, I think nobody has replied as there have been quite a few similar posts over the last few days about what type how do they work how much do they cost etc. Lots of other threads to read just type cgm into the search bit and you should get plenty of info.
I'm getting one for Christmas this year. As far as I can tell from various posts this year and other research I've done it's the most accurate and doesn't have much of a lag compared with the others and when it's paired with the pump I have it's cheap as well (compared to the others it's definitely not plain cheap!), I only have to purchase the transmitter and sets £500 for that and 4 sets. My pump company suggests 1 weeks use from them, the manufacturers suggest 2 weeks use but I've read people getting up to 4 weeks use if you put new sticky stuff on so they don't fall off. For me it's worth the cost of the £50 a month or so it will cost, to improve my HbA1c and the less hassle of having to get my tester out strip down wash my hands test correct then get suited back up again (I work in a lab with microbes not easy for me just to stop and start) but with this it should alarm if I go past certain pre set levels and if my levels are still within range but jump suddenly up or down. I'll just have to press the top button on my pump to see where I am and what my trend is. Also it will help me organise basals for these pesky hormones and help with bolus timings which I'm getting a bit lazy about.
