That’s one BIG reason I didn’t opt to try Animas when they were new… because they were just “too” new at the time (2001) but I did give them more consideration when I was pump shopping last summer and I am quite happy with my Ping, and I haven’t second guessed my pump choice for a minute… MM hadn’t really changed much at all from what I had last (a 512, if you discount that they added CGM to the 522, it’s still basically the SAME pump with almost identical software), and it certainly seemed to have enough shortcomings for me (i don’t know why, but I went through 18 or 19 paradigm pumps… all failed for various reasons) that I didn’t prefer to get a pump that was basically the same… with likely the same issues, when there was a pump that looked like a better match for me.
I think it’s good that there is competition, honestly… it pushes all of the companies to develop better technology to serve all of us. I don’t consider myself brand loyal… I will simply choose the pump that I feel offers the best features for me at the time. For me, reliability is definitely a factor, but I don’t think one necessarily has to go with the market leader to achieve that (my own personal experience wouldn’t label MM as “reliable” - but as with anything, YMMV, there are plenty of people who share my experience, as well as others who have never had any trouble with their MM pumps). There was a time when Minimed was new too, and people had to take a “chance” on them.
