My name is Clemma and I am writing about my experience with the Dexcom Seven continuous glucose monitoring system. I live in Minneapolis with my young son and my not so young husband. I was diagnosed with Type 1 diabetes 11 years ago, when I was almost 21 years old. I started pumping 7 years ago, first with a Minimed 508, then an Animas IR1200, and now with the OmniPod. Friday, June 29 I hooked up to my newest constant companion, the one and only Comrade Dex...

Wish list: Shorter calibration cable, or none at all
The exclusive calibration arrangement doesn't bother me much, because I like the One Touch Ultra just fine, and even if you don't, the whole point of a CGMS is that you don't have to rely so much on finger stick testing.
Then they make you calibrate with a cable. OK, that feels a little clunky to begin with, but I have been told they will put wireless transmission in future models. The thing that gets my goat is that the cable they make you use is like three feet long! (When I get the chance I will measure the cable and report its actual length.*) Of course anyone using this system will coil the cable and keep it in the case that comes with the One Touch Ultra so it doesn't get lost, but this is a big pain in the neck because that much coiled cable is very bulky and the case is the same little case they included with the meter before the cable was added to it.
What makes it really crazy is WHY on EARTH do they think we need such a long cable? When you calibrate your meter, you are sitting right there, you do the finger stick, you plug the meter into the receiver, wait a minute, and unplug. This could easily be accomplished with a 6-inch, or even a 3-inch, length of cable. The only reason I can think of for such a long cable is to swing it over my head like a helicopter when I get mad about a large discrepancy between the meter and the Dexcom receiver. This is one of those features where you wonder whether they REALLY tested this system on people who have to live with it? I mean I know they did, but still, it's one of those thorns in your side that seems insignificant but makes a difference in daily life.
Wish list item #2: Shorter calibration cable while we wait for wireless transmission.
* Update: Read the first comment on this post. Bernard reports that the cable is 6' 6" long. Can anyone come up with a good reason for this?
* Update (Sept 12): I was re-reading the manual the other day and in the specifications section it states that the meter calibration cable is 1' long. Hmmmm. It also says the Receiver charging cable is 6' 6" long. Apparently they are recycling the charging cable for meter calibration.
