Wow! Can you believe it?!? I put a request for a refill for my G4 system along with a transmitter. Turns out, I got a small box today, but it was for a G6 system! I called and was told that there’s a back order and Thanksgiving is also slowing down the delivery. I told the Representative that I only had 1 sensor left. I hope this one works for the entire time ( I’m still in the warm up period). I still haven’t gotten the free right sensor, either! I was told either Friday or Saturday everything (hopefully) is going to come. Not happy at all about this.
