Post two. Last night I lost several hours of feed on the receiver. But I'm sure it was my fault. I hadn't charged the receiver and I think it was just having trouble picking up the signal. I charged it today at work and there's not been an issue so far.
Accuracy today has been about the same as MiniMed. They are usually all within 20 points. I am noticing a faster turn around time. When my blood sugar starts to move quickly (after eating, treating a low, etc) the Dexcom picks up the changes way sooner than the MiniMed. But when my blood sugars are fairly stable, they both are sending about the same results.
I had some questions asked of me in my comments on my last post, so I'll do my best to answer them today. Adhesive: so far it's okay. The very edges of the tape are starting to peel up though, and it makes me wonder if I'm going to make it the full 7 days. I tried to find some Skin Tac here in my (very) small town to no avail. I found something similar, but it was way, way expensive and not worth the money if I chose not to go with Dexcom. I figure I'll tough it out the best I can for now.
Reception: I, too, have to keep my pump and my MiniMed CGM on the same side of my body of the read gets lost. It's annoying at times, but I have a system worked out so that it isn't an issue for me. The Dexcom has a much better range. They tell me it's around five feet. I've not noticed the exact amount. If I forget it somewhere, I'm usually far enough away from it that I'd lose signal anyway. But I leave it on my nightstand and it doesn't have problems picking up a signal, even when I'm sleeping on the transmitter.
Some of the things that I don't like about the Dexcom are the fact that you can't scroll back and see previous readings. I'm used to being able to scroll back on the MiniMed system, so it is a little strange to me. I also don't like that there is no place on the Dexcom to check to see the next calibration time. I'm horrible to forget to calibrate so I always check my MiniMed before I go to be to be sure I don't have to get up in the middle of the night to recalibrate. That being said, I've taken to calibrating both the MiniMed and the Dexcom with my pre-bed testing. So it's not a huge deal.
Let me know if you have tips, questions, etc. I'm here all week! :P
