“The sensor didn't work. My glucose was anywhere from 12 to 50 off. I called Abbott & spoke with a customer service manager. He wasn't very helpful and said to give it 24-48 hours to calibrate. I emailed Diabetic Supplies, the company I purchased the Libre 2 from, but I have yet to hear back from them & it's been over a week. I took the sensor off after 3 days.”
