Super invention! I do not use the Cup though every day during my period, but it is a wonderful alternative to tampon and Co., when you're on the go longer. For my part, notice him (but is not bad and not so unpleasant if times the tampon is wrong). I had to check a few problems if the cup is properly seated - as clamps to be like to a little skin. Furthermore, one must, if one has not quite get the hang of, put a bandage in addition to the slip, otherwise there is a nasty surprise, should not sit properly the Cup. With a little practice the Cup is but a wonderful alternative to tampons! So highly recommended!
