I've very happy with their price - and it was actually cheaper than I expected because I had heard $400. If it wasn't for Nightscout, I would be trying to figure out a way to get them. The iPhones would be an issue for us because we've invested in Android phones to get Nightscout set up. I really don't want to buy iPhones for my kids, especially since the Nightscout uploader phones run about $60 now. It isn't incredibly convenient, but it is an official product backed by and warranteed by Dexcom, which is fabulous. Nightscout, at my house, is set up by me (and I am in no way a tech person) and all problems are handled by me. It's not ideal, though the online group IS incredibly helpful. The Share was my plan and I was expecting to get nothing more than sleepovers and parties out of it. The advantages of Nightscout, for us: ~the kids can use them at school and at sports. With the plug design, Share won't have that ability as the kids change classes every hour and practices/games are often outdoors. ~it's less expensive. It's definitely more complicated but the pieces are cheaper. Cheaper phones, cheap cables, cheap bags. The disadvantage is the monthly phone costs, which Share won't have. We spend $12-15 a month for bare bones cell coverage. ~if I have a concern that someone is viewing their numbers (I can't imagine why anyone would...) I can change it on my own by making a new website easily enough. ~I can view the info in so many ways. I have a browser open in the bottom corner of my desktop at work. If the school calls, I can click and see history to use in decisions. If the kids are having a bad day and I want to stay in touch, I can wear my Pebble anywhere and see the number. I can look at it on my iPad, my phone, all of our computers, my watch. And my kids can wear Pebbles and never need to take their Dexcoms out (except to clear alarms) We are not big users of Nightscout. My daughter takes it to school 4 days a week so that we can check in on her between school and her after school activities. My son takes it twice, I'd guess - once for an afterschool activity and usually another day because of wanting to watch the impact of basal changes. We use it for sports. And parties, sometimes. An hour or two here or there, school a few times a week, etc. It's one of those "really nice to have" things. For us, it's useful. Share would be useful, too, just not as much.
