I agree, it makes sense to be able to function with meters. That is something I did for over 50 years, though fortunately that is now just a memory.
By the way, if your insurance gives you a hassle about buying test strips now that you have CGM, I suggest you get a OneTouch Ultra meter and purchase really excellent 3rd party affordable test strips " GenUltimate Blood Glucose Test Strips 250 Count" – on Amazon at this quantity they cost 36 cents US per strip, so many people can afford to purchase them without depending on insurance. As long as you set the meter code to what’s on the test-strip bottle, they are every bit as accurate as strips from the manufacturer.
In my experience, most G6 sensors are inaccurate during the 1st 24 hours, while restarted sensors are much more accurate after waiting the 2 hours and calibrating. While I like to build up a small supply of sensors in case there are delivery problems, the actual reason I do 1 restart per sensor is being able to avoid the 1st inaccurate 24 hours of a new sensor.
I am impressed that Dexcom has been able to fool the US FDA into believing G6 no longer needs calibration. Good for their shareholders. Not true, in my experience, most of the time, though I am always pleased when a new sensor needs very little calibration, which is about 10-20% of the time.
All that said, I just love my G6 CGM and view the above as a small price to pay for a far better technology than what preceeded it.
But for sure, I also recommend restarts to build up a small sensor inventory in case there are supply delays.
I just wish I could get at least one transmitter ahead for the same reason. I have seen the video on how to pry apart the G6 transmitter, unsolder the batteries and solder in new ones, then glue it all together. I actually could do that – been a ham radio operator for years and all that would be easy – but I just have not taken the time to extend the life of a G6 transmitter.
Based on reports about the upcoming G7, it appears they will thwart all restart attempts with that version, where the transmitter and sensor are combined and thrown away after 10 days (though they hope to exend that to something like 15 days).
Too bad about the G7 reports. Still, I love my Dexcom CGM. In the US, the problems are the very high non-insurance retail prices and how the insurance companies will not allow purchasing a backup inventory.
I am not naive – I know people get glucose monitoring products, don’t use them and sell them to make money. That is sad, and it spoils things for the rest of us…
