Managing diabetes effectively has seen a revolution with continuous glucose monitoring (CGM) systems. Among the top players in this space, Freestyle Libre has carved out a significant niche, offering convenience and accuracy to users worldwide. But with the introduction of the Freestyle Libre 3, many are left wondering: how does it stack up against the Freestyle Libre 2? Let’s dive into a detailed comparison to help you decide which one suits your needs best.
What is the Freestyle Libre 2 Reader?
