I had the first generation minimed RT Monitor with the lollipop transmitter, now that was huge. The dexcom has this small itty bitty transmitter that fits right in the middle of the insertion set. it doesn’t move or jiggle. I considered the new version of the minimed RT monitor, but decided against it since it’s not FDA approved for more then 3 days and that the transmitter is said to flop around unless you tape it down.

the dexcom lasts 7 days well at least 7 days as approved by FDA. and the transmitter just sits there not moving. Also a rechargable batter is nice. What I’d like to see is an iPhone 2 version of a receiver that would reallly rock.

For me, my CDE was able to submit that I have been paying for them myself for years b/c I really need them to control my BG – it’s extremely sensitive and has just about no discernible pattern. If you haven’t used a CGMS before, I would suggest lots of meter logs, especially if these show unpredictable lows/highs or if meter reading don’t match up to your a1c – for example, if you may have weird reading while asleep. The letter from my CDE basically said I was a person who went above and beyond recommended testing requirements, etc and still could not get good results – I’ve never needed an emergency room visit or anything.

My Dex 7 is almost a year old, and doesn’t allow manual entry – I didn’t think they were ready with that yet.

Good luck!
