Can you feel it when walking around with it?
No, it is soft and pliable.
How do you empty it without spilling everywhere?
You just pour it out. If you can manage to put milk in your cornflakes in the morning then you can do it
It seriously doesnt leak?
Some people do have leaks when they are getting used to it. I think it is the most common problem at first, but can usually be solved by proper insertion. Mine has never leaked (fingers crossed) which is more than I can say for tampons
