Just for reference... not trying to convince you either way.
So does she hold it in her hand while she showers? I kinda wanted a waterproof one, but I realized I'm a lot more comfortable taking it off anyway. And 90% of the time when I swim, the infusion set loosens to the point where I feel more comfortable changing it than leaving it in and hoping it still works.
I think most pumps are like watches - they say water resistant because it can't be submersed to great depths for long periods of time, but for all practical purposes they are decent enough.
