Forgive me for not going back through the threads and reading up on this. I need advice now. My son's Medtronic pump broke. It went out of warranty last week. He was thinking of switching to the TSlim because of the touch screen technology. We've been with Medtronic, the Paradigm Revel( Last 4 years), for 10 years. He never liked the Paradigm's CMG because of all of the alarms. My question: Should we switch to a TSlim? Do you like the Dexcom, we've never had that. He is going across the country next year to college. What would you reccomnend? Which one is: user friendly, no issues, company response time, how long do the sites last? We have always been happy with Medtronic, but he wants to switch. I'm just nervous we will switch, and he won't like it. Or, the technology isn't as good as the Medtronic. Thank you in advance for your time.
