While I've had a couple of dodgy sensors over the past 5 years, Abbott has been replacing them without issue.I'm so glad I dont rely on thus unreliable sensor and a company with awful customer service like Abbott
I wont be going ahead with using the Libre2 system
I do use fingersticks alongside the sensors because they can read a bit on the low side for me, and are slow to pick up I'm out of a hypo again, but all in all, they've made my diabetes management a lot easier.
