Hello,
I also have micro bubble problems.They appear when loading insulin from the ball and it is impossible for me to remove them.I have noticed that in the last reservoirs, when I change them, they have a larger bubble formed.I have always had insulin at room temperature, I suppose they are formed to pass the insulin too fast to the reservoir.
Another thing that I see is that in the tub there appear whiter spots, which look like bubbles, but that would say that they are not since putting a bolus do not move.Does that happen to you?
