As a diabetic for the past 30+ years and extremely active person, I really value this new technology. I used DexCom7 for 1 year and Medtronic for 6 months, and I hope my experiences can help you make the best choice. First, any of these is better than none. Nevertheless, I found the DexCom7 to be a far superior machine. Here is a brief summary of the pros and cons of both. DexCom Benefits Positives • More Accurate: Far superior in blood glucose results and they rarely go bad • Great customer service • Don’t need to calibrate as often • Longer sensor life - 7 day sensor • No scaring • More areas for insertion Challenges • Alarm is not very loud – at night, I used an amplifier to wake me when it rang • Alarm only rings every 30 minutes Medtronic Advantages Positives • Less equipment if using a Medtronic Pump • More Warnings of Highs and Lows Challenges • Lack of accuracy: Huge differences between the Medtronic CGM and reality. • Bad Sensors: Sensors go bad often (roughly every other sensor) and Medtronic customer service drills you when you request a replacement • Scaring – Lots more scaring • One insertion site – stomach (otherwise replacement isn’t covered) • Short sensor life –3 days I will be switching back to the DexCom. It is a far superior machine and their customer service is much better. Hope this helps you choose the best CGM.

I was a bit unsure to start using it since it was for the first time I saw such a device .A friend of mine was using it for a long time and assured me it was easy to handle and very easy to use. I was aiming to eliminate the abrupt lows in my daily profile and the high values that I was confronting overnight and thus control my insulin plan. I was a bit unsure about the life sensor but I found that monitors low values and the alarm sounds no matter how low I set the value. But when I was exercising the alarm helped me to prevent a serious hypoglycemia .The alarm was set for 50mg/dl and went on as soon as the value was reached. The variety of sounds one can use for the different types of alerts and the fact that I can introduce data from my daily routine are a huge plus. I introduced my diet in the system and got wonderful results. The system is very smart but I got along with it easily .Wonderful device.

The Continuous Glucose Monitoring (CGM) device is-primarily aimed at detecting and eliminating highs and lows. It is an ideal device in that it can be used with any diabetes treatment plan such as pumps or insulin injections. Another point in favor of the device is that it contains an activated hypo-safety alarm which is used to sense whether the glucose is pegged at 55 mg/dL or lower. The SEVEN PLUS has seven different trend arrow symbols which enable one to know the speed and direction their glucose levels are headed. In fact, there is a variety of sounds for each type of alert such as rate of change alert, out of range alert and custom alert. Lastly, relevant information such as diet and one’s daily activities can also be entered on the system. This goes a long way in reviewing glucose trends and patterns.
