We have been anxiously awaiting the approval of G4 for ages. We received our pink "Dexi" on 10/30 and immediately charged it and inserted a sensor that evening. We had zero luck with the 7+ in the accuracy department. We were just never able to trust the numbers as they would drift frequently and lead to ???. So, initial thoughts now that we have has DD on G4 for 4 days? So far, we've seen some improvement with accuracy and less drifting. Day 1 and part of day 2 were less accurate, but I think the sensor was still settling in. It still strays at times. Also, we have already seen our first set of ???. It caught a low (within 6 points from bG meter reading) and now has been in ??? for 90 minutes. Trying to be patient through this. Here's what we like so far: 1. The range is amazing! It picks her up on the second story of our house from the first floor. We've easily gotten more than 20 feet out of this. 2. It does capture many more readings with fewer gaps in data than the Seven+ 3. The receiver is small, sleek and easier for our little ones to carry. Looks just like an iPod Nano. 4. Color choice. This may not seem like a big deal, but when faced with trying another device, the color option can make it much more appealing to our little ones. 5. The alarms seem louder to me. What we dislike so far: 1. Still struggling a little bit with accuracy. I'm hoping this will improve as I get better at working with the device again. 2. Still no alarm for ??? 3. Still no predictive alarms like Navigator had 4. Already have experienced ??? on day 4 of our first sensor Overall, there are some nice improvements. We still have quite a way to go before these devices incorporate all of the features that would make it feasible to replace finger sticks, but I think we're headed in the right direction.
