I had an Animas pump for 5 years. Back before they were bought my Johnson and Johnson they were fantastic. I never had trouble getting them on the phone or having my questions answered. After the take over I think they cut back the support staff because I was often asked to wait for a call back. Usually the call back never came. My pump went 3 years with out ever needing a call to them. It is a well built product that is just not supported well.
When it was time for a new pump back in January. I called and asked about the new pump. I wanted info about the Ping and Dexcom combo. I also needed a loaner pump because one of the buttons was stuck on my out of warrantee Animas 2020 pump. I got the application to them by email and they never got back to me. Three phone calls and no one responded.
I called Minimed and I had the pump 4 days later. They offered to come to my home and train me. If you call them they always get to you fast.
I find the pumps are pretty similar. It it nice to have the pump and sensor in one unit, but I think the Dexcom is a better product.
Still in the end it is all about customer service, There is nothing that is going to freak me out more than having trouble with my pump and I can't get help.
I am certainly not going to persue a company to give them $6,000 when they do not seem interested in my business.
