You know, I supported your cautionary tale the first time you said it, but honestly enough is enough. You make it sound like parents are endangering their children by using this system or that the only reason they are doing it is to hear the (admitted much better than Dexcom) alarms at night and I can't agree with that. Let me guess - you can put the receiver right by your bedside and see your son's numbers any time you want, right? Well, I can't. My daughter's bedroom is a floor below mine and across the house and it just won't reach. I use it at night to see the numbers and love the alarms and I'm not in the slightest bit concerned about my child's safety while doing it. Geez - even people aren't failsafe; some people sleep through the dexcom alarms when the receiver is right next to them. We had the dexcom long before this so we concocted a way to hear the alarms in our room before this came out and we still have that system in place. But I could never SEE the number and that's what makes this system so beneficial for me. There's a huge difference at 2:00 a.m. when you hear the "dropping" alarm and have no idea without going down a flight of stairs whether she dropped from 160 to 148 (no big deal) or from 90 - 82 (concerning) or whether a low alarm means she has just gone from 90 to 75 and is dropping fast vs. 81 to 80 and might pop back up again in five minutes. Prior to May, if I woke up on my own I would have no idea what was happening, so my choices were to go back to sleep without knowing or to head down the stairs and check and then back up again. Now, I can glance at the numbers from my bed to see what's happening and whether I should try to nip something in the bud before it alarms. These simple things that are available to people who can view the receiver in their rooms were not an option for me. It's like anything else - you don't appreciate the little things unless they aren't available to you. That's why, even if I only use it at night, I'm fine with the money I paid for the system. And it is an expense - I don't readily toss $120+ around without thinking twice.
