I am biased because I chose the dex and I am now under the influence of the endowment effect. I also narrowed my choices down to these two. You have a good chance of being happy with either of them. I like the dex because it lasts 7 days versus 5, has a warm-up period of 2 hours instead of 10, has a smaller sensor with tape that causes less irritation. From reading posts on CWD I sense that many more people switched from Nav to Dex than the other way around. I don't understand the concern "how complicated it his to download". The download consists of connecting the dex to a computer with a USB cable and clicking the download button.

Another happy dex user here! Downloading is very easy, and so I am not sure what the dr is referring to. We usually get much longer than the 7 days, and the transmitter is very small and light. It sticks well and the accuracy is great.

Betty,
How are you able to get more than 7 days? My pocket would certainly appreciate learning how to extend each sensor a bit more. :)

Simply select start sensor. There is no need to touch anything on the transmitter/sensor, just when the 7 days are up, select start sensor on the receiver, wait 2 hours and calibrate. It cannot tell that it is not a new sensor . Also a great way to restart the 7 days, if it will end at an inconvenient time.

The DexCom has caught 99% of my lows in the time I have been using it. I find it scary accurate most of the time. It can get ticky at the end of the sensor life and be less accurate. What turned me off from the Nav was the wetting time. I wanted to be on the CGMS as much as possible and the wait time is so long with the Nav. And downloading the data from the dex is a breeze, just plug in the receiver and open the software, I have never had a problem dumping data. I also suffer from hypo unawareness so I needed something!

The big thing to remember is that no CGMS will be accurate all the time. It is for seeing trends and catching major plummets or rises in BGs. I haven't had a BG over 200 in months because I can see something is going wrong quickly and I can act. And you can get a ton of life out of a sensor. I looked over my logs and I average 12 to 13 days on a sensor. Much easier on the pocket!

I think you sold me Suzanne. How can I find out the price for
everything needed for the DexCom. Can I look at a DVD on
how it works? How long is the waiting time for it to work ?
Does your insurance pay for any part ? Has this company
been around awhile ?

I downloaded the forms from dexcom.com, had my doc sign them and mailed them back to dexcom. dexcom dealt with the insurance. A week later I got my starter kit in the mail.

I had to pay out of pocket for the system plus 1 month of sensors before my insurance started covering it. I paid $1400 ($1000 for the receiver & transmitter, $400 for 4 sensors). Now that I have met the deductible, I pay nothing for the sensors. There are videos on the dexcom site that show you how it works. I am not sure how long they have been around but they have contracts with Animas and Ominpod for integration into those pumps so I think they will be around for awhile.

I love the Dexcom. I chose it, get this, because it's insertion needle is so tiny. I got rid of my HU through its use; I also got my carb grams & insulin dosage where, after a meal, BG never went above 140. You can really learn so much. The inaccuracy comes when high carbs shoot the glucose rapidly up. There isn't a CGM in the world that keeps up with that. It was, of course, lagging real time glucose, and you have to get used to that. All of them do that, too. I learned most by eating one food, seeing what happened and recording it. Plan on doing research on yourself. And have a GREAT TIME with it! Fantastic device!
On the DVD on how it works - download the manual from the site, go through it.
