LOVE IT!!!! We have much more to learn, but here's our first impressions: For us, the predictive low alarm is priceless. Despite backing off on insulin amounts, Nate's trending low a lot, and the Revel is giving us enough warning to ward most lows off with juice or a snack. Over the past 5 days, I've counted two lows (very mild at 74 and 76), and 6 BG's that were headed low but never became low thanks to the Revel. Any juice and snacks given did not cause an over correction, which verifies that he was indeed headed low. We're not yet using the predictive high alarm yet. The alarms, in a side by side comparison to Nate's 722, are higher in pitch and a bit louder on the Revel. I hear them much better than the 722's alarms. The Revel's back light on the screen is brighter than the 722. Fonts are the same, but I can see the screen better because it's brighter. Love the new language in the site change section. It walks you through step by step, asking you to make sure you are not connected when filling the tubing. Also asks you to make sure you see drips of insulin coming out before you insert. Very user friendly. LOVE the Capture Event feature....the navigation through this feature is great. Nate was high (237) the other day. I had him enter the BG via the Capture event menu. When he entered his BG, it asked if he wanted to save the BG, or save BG and use as a calibration. Once we made the selection, it remembered his BG when we went to the bolus section to correct for the high. THIS is awesome...no entering BG's over and over again. LOVE the IOB on the main status screen...very easy to refer to if necessary. LOVE having different low - high threshold settings for different times of day. Not sure if it is my imagination....it seems the few highs he has had on the Revel (highs that we corrected for) came down nice and easy...no sharp and sudden drops. The CGM curves look very nice and rounded off as the glucose comes down from a high. I'm wondering if the way the Revel delivers insulin is different from the 722?? Seems like it does. CGM sensor values in the lower ranges (120 and below) is super accurate for us when compared to his meter BG readings. We NEVER had accuracy like this with his 722. The differences between SG and BG have been a mere few points, several times right on the button. I think this happened once with his 722. CGM range seems a little bit better for us. Under the Utilities menu, I found when using the Daily Totals that the Revel will give you averages for multiple day periods on basal, bolus, carbs, corrections, etc. There's so much more that I am getting used to. I'd like to learn about the AUC (Area Under the Curve) and a few other things. So far, the Revel's a winner in our house!
