  1. I have never used a G6 monitor. I have been using a G7 for almost a month. The G7 has a limited approved insertion site that is not easily reached by the wearer. I have had 1 unit that would not pair and 3 units that have lost signal due to coming loose. So far the longest a unit has worked is 7 days. The company has been good about sending replacement units. I hope that these work better
