The improved range of the G4 transmitter/receiver has been flawless for me. I put the G4 into service on November 2. Excluding the start up partial day and the 7th day 2-hour blackout period, my G4 has not dropped a single data point! Day after day I see a total of 288 (every five minutes or 12 per hours times 24 hours) total data points being recorded.
I used to run two Dex 7+ receivers at night to make up for the inevitable loss of signal due to normal body shifts while sleeping. The new G4 has not missed a single five minute update! Very impressive.
This is a big improvement over the 7+ system as I did have some hypoglycemia incidents at night that the 7+ delayed alerting me to due to a loss of signal.
Is my experience typical? I'd be interested to hear what the other G4 users are experiencing.
