For those of you that have tried both can you give me a breakdown of how you feel about both systems? I am thinking in June when my Medtronic monitor warranty expires to switch to Dexcom. My main concern is Bethany's skin and keeping the sensor on in the pool. I have a good system in place with the Medtronic which involves lots of opsite. I even use it as a barrier for the small amount of tape on the Medtronic sensor. Bethany has a skin allergy to the Omnipod tape which I manage with cavilon. From what I see in the pics, the Dexcom uses the same tape but I don't think I can use the cavilon for a sensor. Also the tape on the pod inevitablely pulls up on day 3 after lots of swimming and the Dexcom you wear for 7 days. Can you tape over the whole thing like you do with the Medtronic sensor and transmitter? I am thinking that tape won't withstand an active 8 year old who loves to swim. Thanks for any input you can give me.
