I have the new ANIMAS IR 2020, LOVE IT!! Especially love the food list ;-)
The only thing I find is that it will give you the history,....however it won't automatically revert to weekend / weekday basal rates.
Which for me, I take more during the work week (go figure) and sometimes I forget to set it to weekend on Fridays and vice versa. So at times, I'm getting too much or too little of a basal.
