It took a while, but I'm happy with my AUS.
No real issue getting used to it. I read how you use one hand to steady the device & the other to press the pump.
Never did that. I pull the device to one side with 3 fingers & press the pump with the other 2.
As long as your dexterity is ok, it should be fine.

Recovery from the actual surgery was no fun, but worth it in the end. Life-changer.
