I was disappointed to find out that my daughter's second receiver broke last night. It stopped making noise. I keep it on attentive so it would still vibrate, but no audible alerts. Luckily we have Nightscout and those alarms continue to work, so I'm not overly anxious. I think I'm just disappointed in the fact that this will be the third receiver in a year. The first one was a charging port issue (not related to Nightscout. I was charging it overnight and it vibrated right off the bathroom counter and was hanging by the charging cord and that broke it) and now this one is an alarm sound issue. On the whole, my daughter and I are very light on electronics/machines. Phones never get broken, iPods and computers last forever, I'm not hard on cars, etc. It's just so foreign to me to have these issues. Plus I can't stand how you can't merge the dexcom studio reports from different receivers - that's probably the biggest beef. I don't think I would care if the new receiver were a seamless transition within dexcom studio. So, I thought I'd ask the question . . . how many receivers do you/your child go through in a year? Are we just unlucky or are these the most fragile things on the planet?
