I have only had my mooncup for two months, but I love it already. Its great not having to remember tampons etc.
However, I would not recommend this for anyone squimish about blood or their own body- I am normally fine with blood but I did feel a little faint the first time I removed it and saw all the blood! But you get used to it very quickly: it is great to completely forget about it and not have the worries about leakage which you get with tampons, nor any of the dryness.
I would also recommend that you use it the first few times when you have plenty of time and space to learn how to remove it, especially as sometimes you need to shift position etc - it would not be ideal to be using this for the first few times in a small cubicle, for example.
