Charlotte (11yo) has been using the Animas Ping for almost nine years now. She's had a Dex (G4) for the last 5 or 6 years. I don't know much about any other products because what's she's been using has been working well. Her Animas warranty is up in May. Her Dex is out of warranty and in the last week has quit sounding alarms when it needs to. I need to replace the Dex asap, but since I will be pump shopping soon, I'd like to know what all my options are. Any suggestions or links to pump comparisons?
