Frankly, I did not expect a reconditioned G5 transmitter to be that good. I purchased the Lifeline-Direct G5 transmitter when switching from G5 to G6 Dexcom supplies. My plan was to buy one transmitter and use it with my pile of unused G5 sensors (which are easy to save because - unlike the G6 sensors - they can be used for up to 3 weeks). My plan was to delay use of G6 transmitters and sensors by three months, while having them delivered and accumulating. That way, I created a three month slack/spare period that I can use to avoid any interruption to my future use of G6 supplies (that are nominally "free" but strictly time-apportioned by my insurer and supplier). Thank you Lifeline-Direct! The delivery was fast (2 days by USPS).
