Ad on YouTube that claims that a simple oximeter can measure blood sugar, blood pressure and more. Ad uses the logo of the famous Charité hospital in Berlin. That hospital has a dedicated page on their website [1] warning about this scam. I report it to Google as being a misleading ad that makes false claims. Well.
