Hello, I’m sadly using them, never had suck a useless. GM ever, I have had your problem, I switched to a different batch and that clears up, I am getting the out of calibration now, last night it was a massive 5 out, ready 9.6 when I was actually 4.6 and dropping!!
Now the Simplera has manufacturing problems, we are all being transferred to the “Faffing about Guardian 4 “ never know a CGM to be so **** complicated to put on?
I know why Simplera is useless, it’s made by Abbots and their Libre 2 were the same.
I hope you get it sorted
