I have the mooncup have had it for about 12 months. I ummed and aaaghed about it for a few months but kept reading the threads on BB and thought why not. I already use tampons and sometimes towards the end it was too dry and I couldn't wear them. I am not big fan of pads as I hate the smell lol!
I don't have very heavy cycles so easily can wear for 8hrs a day and night with no problems. No leakage as someone else said probably had more leakage with tampons. You just have to fold and insert as high up as possible and give it a slight twist to get it to unfold. There are also little holes around the top that you just make sure are not blocked as this is what provides the suction holding it in place. I cut the whole tail of mine as that is what can cause some discomfort you are not supposed have anything outside the vagina. To remove you just bear down and slide you fingers around the side to release the suction of the rim.

Cleaning same as someone else said usually in the shower but you can wipe out with tissue and re-insert. The mooncup is latex too and is easy to insert dry.

No smell just the normal blood smell on first removing. They do change colour slightly overtime but nothing too major. I clean my with non fragranced soap during my period, then boil at the end and store in it's pouch. I purchased mine off the mooncup UK website and they mailed it to me. It also comes in it's own little material pouch to store it between cycles or for in your bag. Approx $50. It took a few goes of practicing first time to get it high enough. It feels a bit funny to start with until it settles in (a bit like tampons) but then you forget its there.

Just had a quick look and it holds 15mls before it is too full. I am lucky to get to half way lol in 8hrs. They come in 2 sizes A and B and this depends on type of child birth and age.

Sorry just re-read and I am all over the shop with my answers and very long. Hope this answers a few of your questions. Also if you look at the mooncup website it has FAQ which I found useful.

Good Luck Leasha, I have never looked back it was the best decision I made.
