My wife of 59 1/2 years has been a brittle Type 1 Diabetic for 58 + years. We've worked as a team to manage her diabetes. She is in the process of being upgraded with a new pump and changing from the G 6 sensors to the Guardian 4. The upgrade is not complete and we were out of the G-6 sensors with none available from her Dr. and we were back to finger sticks. In desperation, I went online and found Lifeline-Direct. I took a chance and ordered a sensor out of pocket. You guys came thru like your advertisement said and I could not be more pleased. I will use you again at first need and will recommend you to others. Thanks for being there for us. My experience with Lifeline-Direct was Great!
