SCIENCE! Dex 7+ vs. G4

So I got my G4 finally, and had a couple of 7+ sensors left. I decided to conduct science and wear both of them and see if either was more accurate or any general conclusions I could make about the new G4 or the old 7+.

So I put them both on opposite sides of my stomach. The G4 was taller, but with the same footprint (more or less) as the 7+. I used an alcohol wipe to prep my skin and clean off the sensor before I put them in, and then stuck an IV3000 with a hole cut out over both. 

G4, says right on it. It's about half an inch tall, I think. Annoying because it seems like it's not snapped in all the way.

7+ sensor. Smaller and closer to the skin, I think better engineered overall.

 I know that the new G4 sensor is bigger because it has more of the "brains" in it, but it's annoying and I think that they could have left that stuff in the receiver and just redesigned it (make it square instead of annoying egg).

A couple hours after calibration, they're close enough together for government work. And the graphs are nearly identical, G4 has better labeling in terms of time though.

Look at that.

I would have taken more pictures but I lost interest in constantly comparing the graphs. Suffice to say they seem to be identical in technology, except that one is presented more appealingly.

7+ has a shorter battery life, probably because of the insane backlight and the length of time it stays on. The light goes out on the G4 faster, but not too fast to read and comprehend it. Both have really annoying LOW <55 alarms, but the G4 is more annoying. I kept them both solely on vibrate, and it seems like there's more of a pattern to the G4's vibrations than the 7+'s.

G4 has a microUSB port! Except there's a cheapo slidy bit to prevent dirt and stuff from getting in it that will be the first thing to break - they should have done a rubber cover thing like on most digital cameras.

In terms of sensor life, I actually had to rip them both out after 4 days because of itchiness and adhesive failure. The G4 gave me a 67 or something when actually my BG was 144 or so. 7+ was right, and I noticed that the adhesive was going on the G4 sensor - I think the wire was out. I took it off because it was really itchy anyway and then took out the 7+ an hour later.

I think that's more of a result of a) stomach is the worst place you could put them and b) I sleep on my stomach etc so a lot of rubbing etc to the sensors than it's sucky adhesive. I haven't yet done an arm G4 but I hope they will be similar to my experiences with the 7+ which is that they last nearly forever (until the sensor wire conks out).
