I have never had so many issues with a product.. EVERY time I have taken a test using this product, my reader somehow gets disconnected, and then it will not tell me my results. It thinks I'm not connected to the internet despite every other internet app working. Doesn't matter if I'm on WiFi or Network.. always disconnects and won't reconnect. I've updated, made sure everything stays plugged in and charged. The most frustrating product ever.
