Well I remember when omni pod came out also, and they didn’t fail. But omni had something the patients wanted, and so does t:slim. I think they will be around for a while, well I’m banking on it since I purchased one. They now own the patterns from the Cosmo and are partnered with dexcom, also working on a dual pump as well.
The way I see it because they have something people want I don’t think they will fail, at worst they may get bought out by one of the major players for the technology.
