I'm finding it very messy to remove, empty and clean out (have emptied it twice today). I cannot imagine doing it in a public toilet.
It also feels very big when inserted, despite folding it up etc as advised in the leaflet. It really isn't as easy to use as I was expecting. It also feels quite big inside, I've jiggled it about to get it more comfortable but I can definitely feel it in there, unlike a tampon.
