And in this corner… (battle of the CGMs)
As my 90-day trial passes the halfway mark, I know I’ll need to make a decision soon as to what I’ll use going forward. Not using a CGM is not an option. Using a SofSensor is a painful choice. Making a multi-year commitment to any one product is never easy.
Enlite v Dexcom? Dexcom v Enlite? So much to consider. I figured that putting my thoughts in words might help me sort things out a bit.
Enlite: Relatively painless, somewhat awkward
G4: Intuitive, relatively painless. My CDE says that most patients can do it well without training
Edge: Slight Dexcom
Enlite: Like unwrapping a compact disc jewelbox from it’s cello wrapping
G4: Like removing a 9-volt battery from its retail packaging.
Enlite: Low-res and somewhat hard to read. Shows tick-marks at each bolus to help explain patterns; allows scrolling back in time. Two levels of trend-up arrows and two levels of trend-down arrows.
G4: High-res, easy to read. Not a fan of using “red” for high, as the color incites rage on top of the inherent high-BG frustration. Three levels of trend-up arrows and three levels of trend-down arrows.
Enlite: Small with smooth curves. Floppy due to side-connector. Difficult to secure comfortably in place. Pressure on transmitter may cause sensor to lift out of skin.
G4: Big and boxy, snaps securely into place. Visually hides sensor.
Edge: Slight Dexcom
Enlite: 40-minute memory will backfill data if it goes out of range of receiver/pump. Rechargeable.
G4: Long-range transmission to receiver. Must be replaced when battery dies – often without adequate warning.
Enlite: Built into pump; no additional receiver needed. Shows “behind-the-scenes” data such as ISIG.
G4: Extra device to carry around — carefully, or the buttons fall off.
Enlite: Predictive; highly customizable – can program different thresholds with time of day. May be hard to hear at night.
G4: Only one high- and one low-threshold. No predictive alerts. Dex-in-a-glass workaround.
Enlite: Three. Carefully and delicately layered. Like a lasagne.
G4: One. Maybe two towards the end of the week.
Edge: Dexcom (maybe Enlite is more suited towards professional gift-wrappers?)
Where can I buy supplies?
Enlite: Directly from Medtronic
Edge: Strong Enlite (your insurance may vary)
Enlite: Carelink and Carelink Pro
G4: Not Carelink
Landfill contribution factor
Edge: Slight Enlite (has anyone considered making this junk recyclable?)
Enlite: When it is good, it is very, very good. When it is bad, it is horrid.
G4: Never used it myself, but anecdotes and MARD statistics (whatever that is) say it’s better.
Enlite: Wavers. Each sensor needs about 2 days to earn my trust.
G4: The fact that Insulet, Animas, and Tandem have (at one time, at least) considered integrating the sensor is a good sign.
Enlite: Annoying as hell, but when it saves my life, it will all be worth it
Enlite: Some reviews are warm, many reviews are fuzzy. None give me that warm-and-fuzzy feeling.
G4: It got 4 1/2 stars on Yelp
Enlite: Resembles some sort of Medieval Torture Wheel, or perhaps a stunt on Super-Sloppy Double-Dare.
Edge: Dexcom – but who cares?
Would I be comfortable if it powered my closed-loop artificial pancreas system?
Edge: Dexcom (but I’m not using closed-loop)

Executive summary: There is none, because I have no freakin’ idea. But one of my goals in this trial was to see if the Enlite sensor was a good enough improvement over Sofsensor for me, and my confidence in that is, at this time, inconclusive.
