Experience in Diabetes (Blood Glucose Monitoring)?

Have you invested or were looking in the past at diabetes business? We're looking at a manufacturer of Blood Glucose Monitoring devices in Europe and would love to speak to someone experienced to learn more about key trends/ technological risks. We are already after few expert interviews, our research and know the leading US listed companies & their offerings. Posting anonymously, as the deal is under quite strict NDA, but obviously I'll reveal my identity when we speak :)
