We hope that the Tandem system will be more transparent and flexible, and much less user-hostile than the 670G. And the Tandem system will give correction boluses when needed, not just basal tweaks, so there is hope that it will not lead to the multi-hour highs in the 300s that haunt some users of the 670G. But the 670G is available now, so that’s something.
That is important for those of us prone to alert-induced rage. This consideration of the user’s emotional comfort, not just clinical safety, reflects well on Tandem.
