I haven't tried conveen sheaths; my leakage is low volume and, up to now, that solution seems a bit 'over the top'. However, in the absence of any solution to my issues with using pads, I may explore that possibility.
I've been reluctant to try the clip-stop gadgets as I've seen so much negative comment about their use. I'd certainly be interested to hear from anybody who has had a positive experience using them.
As I previously said, I can't believe that I'm unique in experiencing problems with using pads and had hoped that somebody might have some experience to share that might help.
